PHP 4.0 Bug #3204: Segment violation during Zend session shutdown

From: jmat@firewind.net Operating system: Linux Redhat 6.1 PHP version: 4.0 Latest CVS (13/01/2000) PHP Bug Type: Reproduceable crash Bug description: Segment violation during Zend session shutdown I can't pinpoint the script/function that's doing this, as it seems to happen in all sorts of things, at random times. The only indication something was wrong is the error logs: all data seems to be pushed out to the browser right as it dies, so no data is lost to the client. Here's the gdb...
