The behaviour that a C programmer should expect from that piece of code is undefined behaviour.

It is the best C compiler I know, together with DEC's. The TenDRA compiler is also very good ... it's a shame that it is not maintained anymore. From a standard C language point of view, gcc sucks pretty much. I think gcc is not even a C compiler, if you take the C standard strictly. > You would be amazed at the things it lets by that are wrong. The above code is not wrong. It's perfectly legal C.
