Do you have DJGPP to compile it or do you want both binaries with compiled debug info? I also wonder about that when commented this lines it stops crashing...
Maybe it's due to I don't fully understand the inline assembler parameter hadling, especially 3rd section clobbered_registers
asm ( "statements" : output_registers : input_registers : clobbered_registers);
maybe when I list my used registers here i don't need to push/pop anything. Maybe I should add save/restore EDI or as you said rewite to use only EAX,EDX,ECX. Can I expect that this regs will not change when entering ring0 and return back?
