I take this back. Removing "extension=mhash.so" from my
/usr/local/etc/php/extensions.ini file does, in fact, exit without a
core dump. However, mhash is required by SquirrelMail along with some of
its plugins. I'm unsure how this will effect SquirrelMail, but
regardless of where I place the mhash.so extension in the list, it still
core dumps (I've tried every possible position.)
