Hi and, er... HELP!

Does anyone know if there's a problem with the GNU library memory
allocation functions, specifically calloc()? All seems to work
fine for normal situations, but if I call calloc() - as shown
below - with numSprites set at a ludicrous value of say, 20000,
the 'after...' message never gets displayed. This leads me to
believe that, in this situation, calloc() never returns (not
even with a NULL pointer) and the whole system hangs :(

GsSPRITE *p;

printf("before...\n");
if ((p = (GsSPRITE *) calloc(numSprites, GsSPRITE_SIZE))==NULL)
	printf("\nFailed to allocate memory for sprites\n");
printf("after...\n");

I came across this problem while trying to track down another
bug, so I would like to get this sorted before I continue (Mmmm,
lovely debugging session without the aid of a debugger).
I'm certainly not a 'C guru', so I may be missing/doing something
really stoopid. BTW, I'm compiling with 0 optimization and
linking to the default 0x80100000 address, if that helps.

Thanks in advance,

Chris
