backtrace from segmentation fault

I'm having a problem with the discussion group software Phorum. After following instructions in the php faq, I'm including the backtrace from the segmentaion fault. Here it is: Program received signal SIGSEGV, Segmentation fault. 0x4 in ?? () from /lib/libresolv.so.2 (gdb) bt #0 0x4 in ??
