Hi

We observed a core drop in the following location.

Program terminated with signal 11, Segmentation fault.
#0 0x212cf8f4 in strncasecmp () from /usr/lib/libc.so.4
(gdb) bt

Is there any known condition / problem that would cause this ?
Can a check be added in strequal.c to see if the pointer is valid , instead of dropping core ?

Thanks
