Re: PHP4 Bug #1768: Code crashes PHP when it tries to print warning

This works for me on Win32. Does this also happen before by libzend patch? Andi At 08:55 PM 7/20/99 +0000, zmievski@ispi.net wrote:

This makes it crash, on Solaris at least. -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: php-dev-unsubscribe@lists.php.net For additional commands, e-mail: php-dev-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
