Application segmentation fault, only when compiling on Windows with MinGW

I'm trying to compile one of my games on Windows, but unfortunately, no matter what, I'm getting this segmentation fault every time I run the program.

Compilation is successful, and without any warning.

Program received signal SIGSEGV, Segmentation fault.

__chkstk_ms () at ../../../../../src/gcc-4.8.1/libgcc/config/i386/cygwin.S:172

172 ../../../../../src/gcc-4.8.1/libgcc/config/i386/cygwin.S: No such file or directory.

I've tried:

I've built all dependencies from source multiple times, tried linking both statically and dynamically.

Debugging doesn't help either - GDB gives me that error message just upon entering main(). I've used -g3 and -O0 flags.

How can I figure out what's happening?

On Windows, the default stack size is smaller than Linux. __chkstk_ms appears to be a function that crashes if you overflow your stack.

You may try to figure out where in your code you are creating huge stack variables or doing very deep recursion, and fix that.

Alternately, you may be able to add a compile flag to increase the stack size. See http://trac.sagemath.org/ticket/13960.

Try to increase stack size. Don't ask me how, I don't know.

The failing call (__chkstk_ms) looks like internal routine which checks if there is enough stack space for the function about to be executed.
