See the original bug report for the exact libgcc.so version and the CFI that caused the issue. It was on the machine that I gave you access to last week. https://lists.fedorahosted.org/pipermail/elfutils-devel/2013-December/003639.html > I have already tried ppc64 (with ppc biarch enabled) on RHEL-6 and F-19 and > both machines PASS all the testcases (one is SKIPped). Yes, they only needed one patch [tests: backtrace.c only check we caught the last instruction on x86_64.] which is now on master. Cheers, Mark
