Comment (by eelco):

 It took me a bit longer than expected, but I can confirm that ghc 6.8.2
 built succesfully using XCode 3.1 (from the iPhone SDK package).

Comment (by eelco):

 I believe XCode 3.1 is released as part of the iPhone SDK
 (http://developer.apple.com/iphone/).  I'm not sure if it's going to be
 released 'stand-alone' as well.  I'm now installing it, to test if the bug
 is fixed for that version.  I'll report back in a couple of hours ;)

 Great, thanks Thorkil!

 So, I think the plan is to just sit and wait? If someone could shout when
 Xcode3.1 is released, that would be very useful.

Comment (by thorkilnaur):

 I am delighted to report that I was unable to provoke the "Bus error"
 reaction using the "Developer preview" version of Xcode3.1 that I tried
 out, prompted by the Apple response. The "tnaur PPC OSX stable 2" builder
 (which is a Mac OS X 10.5 Leopard) has succeeded for the first time, ever,
 with this version of Xcode3.1 (see
 
http://darcs.haskell.org/buildbot/all/builders/tnaur%20PPC%20OSX%20stable%202/builds/90).

 I suggest that we close this ticket when Apple releases a version of Xcode
 with this problem solved.

 Best regards
 Thorkil

 I got this error today
 {{{

 whilst attempting to build the gtk2hs package for ghc-6.8.2.
 My machine is a PowerPC, running Leopard 10.5.2, and the ghc is the one
 from the ghc binary download page for powerpc-tiger.

Comment (by thorkilnaur):

 Apple has responded to the "Bug ID# 5655246 (PPC Leopard (Xcode 3.0)
 linker ld gets "Bus error" sometimes)" that I reported a while back,
 saying that this issue has been addressed in "the latest seed release of
 Xcode 3.1, build 9M2165" and asking for an update of the bug report. I
 will get to that within the next couple of days.

 Thorkil

Comment (by thorkilnaur):

 Thanks for making me aware of the Mac OS X 10.5.2 update. I have updated
 the "tnaur PPC OSX ... 2" builder accordingly, so if that removes the
 problem, we should be able to detect it soon. (For the HEAD, we have to
 await the resolution of http://www.haskell.org/pipermail/cvs-
 ghc/2008-February/041135.html that currently makes the stage 2 build fail,
 rather than the problem of the present ticket.)

 Best regards
 Thorkil

Comment (by eelco):

 I haven't spent much time on this (because I compiling GHC wasn't the
 final goal ;), but the compiler built with 'quickest' gave some strange
 errors concerning interface files when trying to build HAppS.  So I tried
 building 6.8.2 again, again with ld_classic, but now with build flavor
 'quick'.  I had to restart the build 3 or 4 times, since it segfaulted on
 (seemingly) random files.  After that I tried building HAppS again.
 Unfortunately, I got stuck at the same point, this time with a panic.

 Sorry, this must have been caused by something else.  A completely clean

 Hi Thorkil,

 I encounter the dreaded 'Bus error' also when trying to build GHC 6.8.2 on
 PPC OS X 10.5.  It fails on the network library when building with
 extralibs...

 ... and when trying to link HSghc.o in stage 2 when building without the
 extralibs.

 I also tried using ld_classic, simply by running ./configure --with-

Comment (by thorkilnaur):

 I have reduced the size of the assembler file that tickles what I still
 believe is a Leopard linker error to this:
 {{{
 thorkil-naurs-mac-mini:split438 thorkilnaur$ cat g17.s
 .const_data
 .align 2

 _s58i_info:
 .long   0

 .symbol_stub
 L_u_iswalpha$stub:
 .indirect_symbol _u_iswalpha

 lwz r12,lo16(L_u_iswalpha$lazy_ptr)(r11)

 .indirect_symbol _u_iswalpha
 .long dyld_stub_binding_helper
 .subsections_via_symbols
 thorkil-naurs-mac-mini:split438 thorkilnaur$
 }}}
 I get the Bus error as follows:
 {{{
 thorkil-naurs-mac-mini:split438 thorkilnaur$ gcc -c g17.s
 thorkil-naurs-mac-mini:split438 thorkilnaur$ ld -r g17.o
 Bus error
 thorkil-naurs-mac-mini:split438 thorkilnaur$
 }}}
 Here are some things that I can do that removes the Bus error reaction:
  * Change the initial {{{.const_data}}} to {{{.text}}}.
  * Change {{{.long
 
_parseczm2zi0_TextziParserCombinatorsziParsecziToken_makeTokenParser_srt-(_s58i_info)+24}}}
 to {{{.long 0}}}.
  * Remove the entire tail of the file that begins with {{{.symbol_stub}}}.
 http://www.haskell.org/pipermail/glasgow-haskell-
 users/2007-November/013447.html reports that:
   The ld executable used is actually from the ld64 project and not the
 cctools
   project. The cctools' ld is installed as ld_classic on OS X. In theory
 this
   should be the same linker as on Tiger and could be used instead of the
 ld
   from ld64. That might be a good workaround till ld is fixed: Update
 ghc's
   !SysTools to use ld_classic instead of ld.
 This is confirmed by the behaviour of the Leopard linker compared to the
 Tiger linker, in particular the wording of error messages when reporting
 on the same error.

 I have not found a way to replace {{{ld}}} by {{{ld_classic}}} in the GHC
 build process. I have tried:
  * looking for ways to make gcc use ld_classic and, in turn, GHC call gcc
 to make this happen. I have not found such a way.
  * creating a static link earlier than ld in the path that points to
 ld_classic, but this fails to replace the ld uses by gcc
  * replacing the link {{{/usr/libexec/gcc/powerpc-apple-darwin9/4.0.1/ld
 -> ../../../../bin/ld}}}, but that causes GHC configure (and also ordinary
 gcc compiles) to fail with
  {{{
  /usr/libexec/gcc/powerpc-apple-darwin9/4.0.1/ld: /usr/lib/gcc/powerpc-
 apple-darwin9/4.0.1/../../../libSystem.dylib unknown flags (type) of
 section 9 (__TEXT,__dof_plockstat) in load command 0
  /usr/libexec/gcc/powerpc-apple-darwin9/4.0.1/ld:
 /usr/lib/libSystem.B.dylib unknown flags (type) of section 9
 (__TEXT,__dof_plockstat) in load command 0
  collect2: ld returned 1 exit status
  }}}

 The basic problem that the Leopard linker apparently fails to solve in
 some cases is the evaluation of the expression
 
{{{_parseczm2zi0_TextziParserCombinatorsziParsecziToken_makeTokenParser_srt-(_s58i_info)+24}}}
 in line 7 of g17.s. The two symbols are defined in different sections
 (.const_data and .text, respectively) which seems significant. But whether
 this indicates any reasonable workaround in, say, the GHC code generator,
 I cannot tell.

 In any case, I would welcome some ideas about further directions for this
 investigation. I will happily supply any additional details.

 Best regards
 Thorkil
