php 4.0.1 and error_reporting

Has error reporting changed somehow between PHP 4.0.0 and 4.0.1 because I'm getting random notices about uninitialized variables and constants in my scripts after I upgraded to 4.0.1. The notices don't show up every time, but when I press reload, they show up on constant intervals, about 1/5 of the time. I have the default error_reporting (E_ALL & ~E_NOTICE), phpinfo() shows error_reporting 2039. The problems go away instantly when I downgrade to 4.0.0. PHP compiled as Apache module (DSO), platform RedHat Linux 6.2, Apache/1.3.12 Ben-SSL/1.39. Configure-line is: ./configure' '--disable-debug' '--with-imap=/usr/local' '--with-pgsql=/usr' '--with-mysql=/usr' '--with-gd=/usr' '--with-freetype' '--with-apxs=/usr/bin/apxs' I'm using Zend Optimizer. -Kari -- Kari Asikainen Ilamark Oy tel: +358 14 716155 mobile: +358 40 525 9842
