No messages?

It must be getting past the bad point to a worse point.

A silent reboot happens from a triple-fault, usually.  Can you buzz-loop
faults in assembly to blow it out?

This may not be possible if the culprit is stack corruption.

I would put in:

{
int i;
printf( "here 1\n");
for( i=0; i < 0x7fffffff; i++)		/* adjust down for time*/
	continue;
}

for a bunch of different "here" locations and see where it fails.

There are probably better people to ask about debugging; I usually
use printf.  8-(.
