Why are you dooing this? Specifying the program entry point
yourself means, that you totally omit the runtime libraries
initialisation code. This code does im****tant things: Set up
dynamic memory management structures for malloc, set FPU
registers, and in case of C++ calls static constructors.

Well, yes, but you will then be unable to set things like window
geometry and stuff by command line parameters.

Could it be due to the simple fact, that libc isn't initialized
and thus any call in a function of it may hit uninitialized
structures?
Did you try those self defined glutInit parameters from within a
ordinary main?
