I'm not sure if this is a problem with my programming or something else, which is why it is Programming Questions.

I have a part-finished game that works fine in Linux at home.
I've spent the last three quarters of an hour convincing Dev-C++ that it is in fact compilable (why the hell isn't allegro-config available in Windows?).

Now when I try to run it I get a generic Windows crash message, which I can only assume to be a segfault. It says the program has encountered an error and needs to close. When ran from gdb it claims that there is an error, of number 193. From a bit of Googling I believe this to be a bad executable format.

Does anyone know what I might have done wrong to cause this?
The game uses AllegroGL and Allegro, and is linked with:

-lagl
-lalleg
-lopengl32
-lglu32
-lgdi32

Which I found from Googling. I am compiling with -g.

(gdb) run
Starting program: E:\programs\Apero/apero

EDIT2:
I'm a dumbass.
I should be doing gdb apero.exe, not just gdb apero.
Turns out the stack pointer is being overwritten.
