I've just downloaded the python source code and build it myself, the compiler settings in our project is the same as in the python projects. 


Though, your comment led me in the correct direction. When using the libs/binary I built my self it let me see the values of the PyObjects around the crash and it seems like it is related to our modules and/or how we expose them to the interpreter. When disabling our own modules everything seems to be working as it should. 

I think I got it wokring now, used some ugly hacks I need to clean up before I certain it works. 

Thanks for the help.
