[Gluster-users] glusterfs 3.1.1 troubles on SLES11 SP1

Tue Sep 13 18:46:36 UTC 2011

This looks like a compiler bug in SLES SP1. I have a standalone test case
here to prove it is a compiler issue -

https://github.com/avati/gcc-bug

It is scary because the data structures ended up getting linked wrongly!!
Compiling without -O2 seems to fix this crash, but we're still not sure how
much of "internal damage" is happening in other places. Pavan has posted to
the gcc list about this bug and maybe we will raise it with Novell as well.
