I have a fairly large DJGPP application, which makes use of mikmod for sound
services, and uses allegro's _install_irq functions for the timer.
(This means there will be a lot of realmode interrupt activity)

If the mikmod mixing kernel is running when the display is set up, the program
crashes with a GPF in RMCB, as soon as a getch() or bioskey() is executed.

The program stops crashing if I set the size of the RealMode Transfer buffer
to be 32k instead of 16.

Any ideas why this is happening, what can I do about it?
Is changing the RMTB size masking the problem or fixing it?
If so, can I set the RMTB size in my program, like the stack size?
(Having to run stubedit after each compile is a pain.)
Alternatively, could I make a new stub with a default of 32k RMTB?
Thanks..
