Bug description: apache segfault on php as module and doesnt serve content
correctly
Description:
------------
apache segfault when php is used as module , not when used in cli or as
cgi. same result , at least for the crash on 3 different php5 versions i
tried including 5.2.5, including 5.2.5 with the bar minimum of
features/modules enabled and all debug i could enabled as well.
the issue doesn t happen when the php module isn t loaded
there s bug that sounds a bit like mine but i tried
APACHE2_OPTS="-D DEFAULT_VHOST -D PHP5 -D USERDIR" instead of
APACHE2_OPTS="-D USERDIR -D SUEXEC -D DEFAULT_VHOST -D INFO -D LANGUAGE -D
SSL -D SSL_DEFAULT_VHOST -D PHP5"
and it still crashed
Reproduce code:
---------------
just try to access any php file via apache to get a crash
try to access any other file to get some error
Expected result:
----------------
i wanted my page to be displayed ?
Actual result:
--------------
