4.2.2 > 4.2.3 - Incompatibility

Hi guys, I've found me a problem... A portion of a script is causing the child apache process to be terminated: [notice] child pid 23620 exit signal Segmentation fault (11) I never had a problem with this script until I upgraded to 4.2.3. The only other difference is that now I have PHP compiled as an APXS module, whereas before it was compiled into apache. The script is below... $pass_gen = substr(ereg_replace("[^A-Za-z0-9]", "", crypt(time())) . ereg_replace("[^A-Za-z0-9]", "", crypt(time())) . ereg_replace("[^A-Za-z0-9]", "", crypt(time())), 9, 10); Any ideas? Cheers, Liam
