	I am having a problem with grx20.  I downloaded djgpp v2 and
installed it.  I then made the test programs for grx20 and ran them.  All 
the ones I ran worked fine.  I had a grx program from djgpp v1 that I tried
to recompile under v2 and run and it bombed.  I was able to reduce it down
to this:

#include <grx20.h>

int main(void)
{
	int t_array[512][512]; 

	/* set graphics mode */
	GrSetMode(GR_default_graphics);
	
	/* clean up */
	/* reset to text mode */
	GrSetMode(GR_default_text);

	return(0);

}

The error I get when I try to run this is:


Exiting due to signal SIGSEGV
Stack Fault at eip=00001545
eax=00000000 ebx=0005f070 ecx=0006404c edx=00000033 esi=00000054 edi=0001e430

Call frame traceback EIPs:
  0x00001545


I don't get errors if I reduce the array size to below 256x256.  The makefile
I used is:



grtest.:grtest.c
	gcc -g -O -Id:/djgpp/contrib/grx20/include\
  -Ld:/djgpp/contrib/grx20/lib -o $@ $< -lgrx20 


I have tried this on two separate systems with the same results.  Any help
would be appreciated.
