[2003-01-13 17:14:36] [EMAIL PROTECTED] for information ther's the same bug on php-4.2.3 compiled more infos. With same parameters (only gd external lib was used instead of 4.3 bundled). But this works fine on Mandrake linux 8.2 system with its own rpmized php (php-4.1.2 I think). Don't know if Mandrake team applied a special patch on sources??? [2003-01-13 16:26:42] [EMAIL PROTECTED] The actual crash occurs inside the pcrelib, so it could pcre related, but since I am unable to replicate the crash using pcre command line tools it maybe PHP related after all.
