Could you provide reproducibility information?
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.

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.
