//#define SL_LEAK_DUMP - got better / more accurate stack dumps when we detect errors in game. - Both of these need to be worked on in windows next, win32 may not compile for now until i fix it on that platform. - BE VERY CAREFUL when working in leak_dumper.* it may cause GCC and your system to crash if you don't know what you are doing!
