libdill failures on FreeBSD with gcc

[bapt]

With gcc: ./configure 1 failure ./configure --disable-threads == same failure ./configure --disable-threads CFLAGS="-DDILL_ARCH_FALLBACK -fno-stack-protector :

With clang ./configure all OK ./configure --disable-threads all OK ./configure --disable-threads CFLAGS="-DDILL_ARCH_FALLBACK -fno-stack-protector all ok

@bapt could you post ./test-suite.log after tests failures

[avsej]

Nevermind, I've got it reproduced on FreeBSD 11.0-RELEASE-p6 with the following steps:

git clean -dfx
./autogen.sh
./configure --disable-threads CFLAGS="-DDILL_ARCH_FALLBACK -fno-stack-protector" CC=gcc49 CPP=cpp49
make check

[avsej]

The minimal flags set is

./autogen.sh && ./configure CFLAGS="-DDILL_ARCH_FALLBACK"  && make

[raedwulf]

The stack trace should work now, let me know if there are any further issues.

[avsej]

The tests are green now

[raedwulf]

@avsej did my commit fix it?

[avsej]

Yes. That was your fix to jump issue

[bapt]

Testing on the latest tree I got: All green with clang

[raedwulf]

I may have some time tomorrow to look at this; for now can you create a backtrace? That should be working now.

[raedwulf]

I can't reproduce this in a FreeBSD VPS with 11.0-RELEASE-p2

Have you tried adding "-Wl,-rpath=/usr/local/lib/gcc49" to LDFLAGS.

[raedwulf]

I'll have some time tomorrow to try it on bare metal

[raedwulf]

Just tested this again on bare-metal and it is working with gcc-4.9. It may have already been fixed in HEAD or FreeBSD has fixed a bug...

If you still have the problem, can you double check your glibc/gcc is up-to-date as well.
