[Issue 17726] Older DMD versions segfault when building Druntime with GCC 7.1

2017-08-06 Thread via Digitalmars-d-bugs 
https://issues.dlang.org/show_bug.cgi?id=17726

--- Comment #5 from Vladimir Panteleev  ---
Segfault occurs on the line:

esave = *e;

The line is inside the evalu8 function, which is also the only function needed
to be compiled with -O2 for the bug to manifest.

[Issue 17727] addr2line does not understand debug info

--- Comment #1 from Shachar Shemesh  ---
Also see discussion at
http://forum.dlang.org/thread/om6cfd$akb$1...@digitalmars.com

It seems that the "break main" issue is unrelated to the debug info, and is
because it has another symbol with the name "main".

gdb, for some reason, does manage to show line numbers, but only sort of:

writeln("Hello, world");
}

To summarize:
gdb can break on function name, but cannot single step from that point, as it
claims it has no line information.

It can break on file:line combination.

addr2line cannot convert that address into a file:line

Narrowed down the file to backend/evalu8.c. (Segfault manifests iff that file
is compiled with -O2).

Minimal object.d:

// object_.d //
module object;

class Object {}
struct OffsetTypeInfo {}
class TypeInfo {}
class TypeInfo_Class { void[136] foo = void; }
class TypeInfo_Struct { void[120] foo = void; }
struct ModuleInfo {}

auto fun()
{
return (cast(int*)null)[0 .. 1];
}
///

`dmd -c -m64 object_.d` will segfault if dmd was built with GCC 7.1 and -O2.

Works fine without "CFLAGS += -O2", so it looks like either a GCC optimizer
bug, or UB in DMD.

I should clarify that the method used was with Digger (e.g. "digger build
master@2015-01-01"). I've just pushed an update with a workaround for the
PIC/PIE issue.

[Issue 17726] New: Older DMD versions segfault when building Druntime with GCC 7.1

2017-08-06 Thread via Digitalmars-d-bugs 
https://issues.dlang.org/show_bug.cgi?id=17726

  Issue ID: 17726
   Summary: Older DMD versions segfault when building Druntime
with GCC 7.1
   Product: D
   Version: D2
  Hardware: All
OS: All
Status: NEW
  Severity: normal
  Priority: P1
 Component: dmd
  Assignee: nob...@puremagic.com
  Reporter: dlang-bugzi...@thecybershadow.net

Although the issue doesn't occur with the latest DMD versions, building older
versions is still important for bootstrapping, so I'm opening this issue to
track the problem.

On Arch Linux, attempting to build D versions from 2015 or earlier will result
in a segmentation fault while building Druntime, e.g.:

path/to/dmd -lib -oflib/libdruntime-linux64.a -Xfdruntime.json -m64 -O -release
-inline -w -Isrc -Iimport  src/object_.d src/core/atomic.d ...
make: *** [posix.mak:172: lib/libdruntime-linux64so.a] Segmentation fault (core
dumped)
make: *** Waiting for unfinished jobs
make: *** [posix.mak:178: lib/libdruntime-linux64.a] Segmentation fault (core
dumped)

On Arch Linux, the build succeeds with the packages:
- gcc-libs-multilib
- gcc-multilib
- lib32-gcc-libs
are at version 6.3.1-2, but fails at version 7.1.1-3.

Arch Linux pushed GCC 7.1 to the multilib repo on 2017-05-30.

D versions since https://github.com/dlang/dmd/pull/4924 build OK with any GCC
version. I suspect that the behaviour changed due to the change in default
optimization flags. This is possibly an optimizer regression in GCC 7.x.
