>Sorry, I don't get your point. >What else do you expect to happen? I don't expect a crash. Why? because the strcpy should simply copy an item to memory location. I wonder why it says "I can not access the memory location where is memory location is the data value"?!!! Why on earth strcpy wants to access a memory location where I didn't tell him to access? Moreover, as I said multiple times, why w/o specifying -m32, the program finishes without error?
