Description of Problem:
mysql-3.23.52-3 seg faults on remote network connects. Using the mysql client,
and running mysqld under the debugger. I get this:
Program received signal SIGSEGV, Segmentation fault.

Version-Release number of selected component (if applicable):
Just wanted to mention that an upgrade to glibc 2.3.1 (built from Rawhide
SRPM's) resolved this problem on our end. So, it is definetly a problem with
MySQL<->glibc interaction (if not a bug in glibc itself).
This bug is similar to bug 75128.
