	An executable generated using gcc with the -g option
does not crash but another exe generated ugin the same source
but with optimizing level set to -o2 crashes. whu??
	Is it because optimizing causes some run time errors that
do not occur in non-optimized code?

	Also, when the non-optimized exe is stripped and run, it
doesn't crash.
	Any hint as to what is happening and how to tackle it 
would be appreciated.
	Any thoughts?
