I installed gbd and with what little i know of it, ran gdb against the dump: (gdb) core /httpd.core [New LWP 101030] Core was generated by `/usr/local/sbin/httpd -DNOHTTPACCEPT'. Program terminated with signal SIGSEGV, Segmentation fault. Address not mapped to object. #0 0x000000083f237930 in ?? () (gdb) bt full #0 0x000000083f237930 in ?? () No symbol table info available. (goes on like this for another 10 lines) I *guess* [1] I'll need to recompile apache24 with debug symbols then wait for another crash. Is there anything else i can do regarding this problem? [1] gdb etc aren't my wheelhouse *at all* but i'm willing to learn, and any tips/pointers would be much appreciated, thanks --
