Comment (by thorkilnaur):
The original problem was reported against a GHC HEAD pulled around
2008-Feb-03. I am warming up my PPC Mac OS X 10.4 GHC HEAD, intending to
see whether the problem is still there.
In the meantime, the PPC Mac OS X 10.5 builders, both HEAD
(http://darcs.haskell.org/buildbot/all/builders/tnaur%20PPC%20OSX%20head%202/builds/138)
and STABLE
(http://darcs.haskell.org/buildbot/all/builders/tnaur%20PPC%20OSX%20stable%202/builds/175),
currently get a report like
{{{
=====> arr001(normal)
cd ./array/should_run &&
'/Volumes/tn18_HD_1/Users/thorkilnaur/tn/buildbot/ghc/tnaur-ppc-osx-2

lint -dcmm-lint -Dpowerpc_apple_darwin -dno-debug-output -o arr001
arr001.hs >arr001.comp.stderr 2>&1
timeout: internal error: stg_ap_p_ret
(GHC version 6.11.20080925 for powerpc_apple_darwin)
Please report this as a GHC bug:
http://www.haskell.org/ghc/reportabug
Compile failed (status -1536) errors were:
*** unexpected failure for arr001(normal)
}}}
for all tests, as far as I can tell. The latest head summary reports:
{{{
OVERALL SUMMARY for test run started at Thu Sep 25 05:40:29 CEST 2008
2138 total tests, which gave rise to
6607 test cases, of which
1864 caused framework failures
1057 were skipped
274 expected passes
167 expected failures
1 unexpected passes
3244 unexpected failures
}}}
I can reproduce like this:
{{{
$ ./timeout 200 'echo Something'
timeout: internal error: stg_ap_p_ret
(GHC version 6.11.20080925 for powerpc_apple_darwin)
Please report this as a GHC bug:
http://www.haskell.org/ghc/reportabug
Something
Abort trap
$
}}}
I have not attempted to investigate further.
Best regards
