This looks like it's probably the annoying prelink issue, since  
libpthread is mapped at a strange address (aka not right after  
libdl). Run:
prelink -u /lib/libpthread-2.4.so
to unprelink that library, which should temporarily fix it, and set  
PRELINK=no in /etc/sysconfig/prelink to keep it from reoccurring.  
(There's a cron script which will periodically re-prelink all  
libraries on the system.)

At least, that's how things were on FC3...I don't know if it's  
different in FC5.
