Additional. Probably has something to do with the API change Zend made in b4

Does this happen with every script? If not, please provide a short! testing script. If you can, please also provide a backtrace.

Seems to occur with every invocation of php, even just simply fetching the version with -v. Running with a <? phpinfo() ?> as input, the script outputs all system variables and the PHP license before seg faulting.

I tried running it with gdb to get a backtrace but it wasn't being helpful, do I need to compile with any special options?

compiler flags being used by default are: -O2 -pipe -march=i686 -fomit-frame-pointer

As stated, everything worked fine until the change from b3 to b4

can you please compile without any of those flags, and add --enable-debug to your PHP configure line? That should give you a much better backtrace. I still can't reproduce your segfault here.
