Description of problem:
After appling the new glibc-2.2.4-30 packages to a system, components of jabber
core dump on a regular expression. Prior to the upgrade this never happened.
When perfoming specific operations, the process is killed with signal 11 (SEGV).
This appears to be a conflict between GNU pth 1.4.0 and this version of glibc.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Launch Jabber with the AOL transport enabled.
2. Attempt to register the gateway with a client.
3. Jabberd process dumps core on server.
Here is a stack backtrace from one of the core dumps:

From what I have gathered, the aim_newconn function is at the point where it
calls the aim_proxyconnect function. in that function the atons is called.
Looking at the symbol dump for the libc that the process is using the htons
function is located at : 000fe1e0 T htons which corresponds to the first
parameter to the fixup function.
I have also seen the process crash with a (runtime) linker error that states the
"htons" function could not be located.
