Crashes PHP (5.5.15) process CLI + apache2handler

[benjamin-carl]

The extension compiles (beside some warnings) with nmake under windows without any problems. As soon the extension is loaded the whole process crashes. No matter if i try with CLI or Apache.
Any ideas what it could be?

I don't have a crashdump or something like that - cause i don't know what you would need to dig into.
But if you tell me i could try to fetch some more details/dump.

I successfully built my extension: https://github.com/clickalicious/php_zopfli as well as uprofiler: https://github.com/FriendsOfPHP/uprofiler (this one is a bit more complex) without any problems in the exactly same build environment. So the environment seems to be functional and the resulting extensions are OK in general.

I assume there were some changes in the last PHP releases (5.4/5.5) breaking functionality of your extension // or maybe some OS issues.

Can you either confirm or deny this assumptions?
