PHP Bug Type: Apache2 related
Bug description: PHP 5.2.0 on Solaris causes Apache to Segfault
Description:
------------
PHP 5.2.0 compiled for Apache 2.2.3 on Solaris 10 or 9 causes to
segmentation fault. I experienced this problem while installing
Squirrelmail 1.4.9a. PHP was compiled on a Solaris 9 system using gcc
4.0.3. I'll try to generate a core file and send it.
PHP Code Example
----------------
print "Hello World"; --> works
phpinfo(); --> works
header('Location: src/login.php'); --> segfault
Apache error_log
----------------
[notice] child pid 9278 exit signal Segmentation fault (11)
Apache truss
------------
