I did the Ubuntu upgrade thing, and it's still happening for me too.
I have no idea how to narrow it down some more.
I had a short conversation w/ Joachim on #ghc, and what we know so far:
For a non-failing linker_unload environment, the testprogram is linked against libgmp.so:
$ ldd tests/rts/linker_unload linux-vdso.so.1 => (0x00007fff20f6c000) libgmp.so.10 => /usr/lib/x86_64-linux-gnu/libgmp.so.10 (0x00007f83c5bbb000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f83c58b5000) librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f83c56ac000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f83c54a8000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f83c50e3000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f83c4ec4000) /lib64/ld-linux-x86-64.so.2 (0x00007f83c5e76000)
Also, in the reported test failure, the failure occurs when calling resolveObjs() on the Test.o file (after the libHS-libs were already succesfully loadPkg()ed)
r = loadObj(OBJPATH); if (!r) { errorBelch("loadObj(%s) failed", OBJPATH); exit(1); } r = resolveObjs(); if (!r) { errorBelch("resolveObjs failed"); exit(1); }
Alas we still don't know what property of the build-environment determines whether this test fails or succeeds... :-/ _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://www.haskell.org/mailman/listinfo/ghc-devs
