I tried the code on my 300Mhz Pentium II machine (MMX).  I
compiled under gcc (gnu-wn32).  The OS caught the problem
and terminated the program without crashing.  It gave me a
dialog box containing the statement:
 
"The exception unknown software exeption (0x000001e)
occured in the applicaiton at location 0x00403004"
 
I was then able to terminate the application or drop into 
the VC++ debugger and proceed.

I'm running NT 4.0 SP 3.
