[Comment 2 Daniel Pielmeier 2010-12-20 08:37:26 UTC]

I guess the new versions of libburn and libisoburn compile?

> I guess the new versions of libburn and libisoburn compile?

dev-libs/libburn-0.9.0 yes, dev-libs/libisoburn-0.6.6 needs libisofs, which fails...

[Comment 4 Daniel Pielmeier 2010-12-20 12:00:54 UTC]

I have contacted upstream about this issue and will add his remarks here.

Although the error occurs in libisofs/messages.c the reported line number seems to be from the generated assembler code. Somehow we need to identify the code in messages.c which generates the failing assembler code. Maybe the toolchain guys can help us out here.

Also can you try if it builds with debugging enabled and without -02 optimisations.

CFLAGS="-O0 -march=armv5te -pipe" CXXFLAGS="${CFLAGS}" USE="debug" emerge -1 libisofs

emerged w/o issues like that.

fails the same way with -O1 as with -O2 (debug USE-flag doesn't matter).

What about -O3? Can you try it as well?

fails as well (+/-debug doesn't change anything)

[Comment 9 Markus Meier 2010-12-22 12:32:27 UTC]

please ignore my comment #0 as libisofs-0.6.38 fails the same way with gcc-4.5.1.
this looks like http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45726 - I'm rebuilding gcc with these patches.

applying the patch from the bug solves the issue with libisofs (and the testcase from the gcc bug).
@toolchain: it would be great if you could integrate it in our gcc patchset - thanks in advance.

[Comment 11 Ryan Hill (RETIRED) 2010-12-24 01:53:38 UTC]

I'll include it in the 4.5.2 bump next week.

[Comment 12 Ryan Hill (RETIRED) 2010-12-28 01:08:52 UTC]

Fixed in 4.5.2.
