Andrei Ellman napsal(a):
When I run the following line from a program compiled with the DOS
version of Allegro 4.2 (compiled with DJGPP):
set_gfx_mode(GFX_AUTODETECT_WINDOWED, 640, 480, 0, 0);
the program has been known to crash with a SIGILL error (illegal
instruction). My guess is that because on DOS there are no windowed
modes, the pointer in some vtable or other is set to a dodgy address.
If there are no windowed modes available on the platform, then the
set_gfx_mode function should just return gracefully with it's usual
failiure-code.
It behaves exactly like that, either you are doing something wrong or
the bug is elsewhere (tested with latest SVN 4.2)
