New Comment:
Has this potentially caused a regression?
I applied the patch that was checked in CVS this afternoon
and recompiled PHP.
Had another segfault in GD, here is the backtrace.
Unfortunately it wasn't a debug build.

__orig_bailout = Variable "__orig_bailout" is not
available.
I can try a debug build but the segfaults are occuring less
frequently now.

Also backported to 4_4.

Any chance of having this backported to the PHP_4_4 branch? It's a
fairly minor patch to apply.

I reported the issue in GD too:
http://bugs.libgd.org/?do=details&task_id=48
Will be fixed in 2.0.35.
Thanks for your patch and nice reproduce case!

This bug has been fixed in CVS.
Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
Thank you for the report, and for helping us make PHP better.
And again - very nice reproduce case & report, thanks.

Should probably class this as a crash.
