segmentation fault caused by pthread_create

[ugexe]

Ok the windows part of the code works fine, but the rest causes a segmentation fault at runtime. I am calling it with ThreadLib::Create(functionName,(void*)'a');

Also, since im not sure if anyone will be able to track down the problem, I would be willing to use a different wrapper as long as it is a cross platform, VERY simple (I dont want a bunch of extra features.. I really only need to be able to create 1 thread other then the main thread), and preferablly 1 file. :(

maybe the error is inside the thread, verify that p_data and his members are valid pointers
