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)
