[Bug 776642] Re: segfaults from 5.2.4-2ubuntu5.15
Hi I just ran into this bug. In hindsight a serious issue that started 3 days ago with one of our web apps seems to also be caused by this. Just tested Steve's patched packages (5.2.4-2ubuntu5.17~lp776642) on our dev server and I can confirm they fix the problems for us.

Thanks for reporting this bug and coming up with a nice, small test case to reproduce it. I've confirmed that it's an issue for 8.04 LTS and 6.06 LTS and I've pulled a patch from upstream's subversion (http://svn.php.net/viewvc?view=revisionrevision=267423) that fixes the test case locally (attached). I've uploaded a test package for 8.04 LTS based on this fix (and the one for bug 774452) to the security-proposed ppa at https://launchpad.net /~ubuntu-security-proposed/+archive/ppa/. I'd appreciate it someone could confirm that the package fixes it for the more complex situation code that triggered it initially.
