--- Comment #1 from Florian Weimer <fweimer at redhat dot com> ---
I can't reproduce this with more recent distribution builds.

There were some issues with the old x86 assembler implementations of locking
primitives, and we have since removed them.

I suggest to reach out to SUSE to see if they can apply relevant fixes to their
distribution. Thanks.
