Apache crash -- malloc: incorrect checksum for freed object -- locks up server and kills moodle

The machine serving moodle here crashed and the only errors I can find are in the apache log:

httpd(3890) malloc: *** error for object 0x1972400: incorrect checksum for freed object - object was probably modified after being freed, break at szone_error to debug
httpd(3890) malloc: *** set a breakpoint in szone_error to debug

I am wondering what would cause this?  I am running the following setup:
Mac OS X 10.4
Apache 1.3.33
PHP 5.0.4
MySQL 4.1.3

Anyone have any thoughts on this?  Should I down-grade to PHP4?  Any other likely candidates?
