Segfault on CentOS 5.8 with 2.1.12

We installed FR on one CentOS 5.8 today, and we are running into weird 
crashing issues.  Sometimes RADIUS works fine, sometimes it starts to 
crash right after the start.  We hooked gdb to it, and it appears to be 
related with the rlm_perl module.  We are using an external perl module, 
but it is running fine on many hundreds of systems.  I am wandering if 
someone have an idea about what can be wrong :

I am not aware of the issue for other CentOS 5 version, or CentOS 6.
