I've been running the yum-stress-cookbook every 30 mins during the
last 24 hours with the latest ruby packages (1.8.7-p352-3) from RBEL5
(CentOS 5.6 i386) and prelink enabled.
libruby has been prelinked at 4am and chef-client is still kicking so
far. No segfaults at all.
It's probably one of the build flags causing the issue. Still need to
find which flag is the evil though. I' believe it's one of the flags
in %optflags available when building inside mock.
I'll keep digging.
