Hi! Everyone,

	My program can be compiled by GCC to generate an execution
file but always crashes during execution. I followed the direction in
the DJGPP FAQ to print out its stack dump.

	I don't know how to deal with my problem with the stack dump
list. Please show me a way to do that. Thanks a lot! 

	The related information is attached to this mail.

Best Regards,

Shue-Cheng Chen
