From: jhuston at cs dot umn dot edu Operating system: Sparc Solaris 9 PHP version: 4.3.3RC1 PHP Bug Type: Reproducible crash Bug description: exit signal Segmentation fault (11)
Description: ------------ Installed PHP 4.3.3RC1 as a DSO on Apache 2.0.47 with the mysql and oracle and gd extension enabled. I was able to reproduce same segfault error on Apache 1.3.27 with DSO enabled. I can also reproduce the same problem from line command. It appears that it does go through to the end of the script but it just dies before it could complete the script peacefully. I'd get the same problem with my other scripts sharing the same set of functions library. I tracked down a possible cause of Bus Error or Segmentation fault. It appears that when the script is doing $_SESSION variable assignments, it puked on exit. When I commented out all lines containing $_SESSION variable assignments, the script exited peacefully without any seg fault or bus error.
