Well, honestly... is this interesting if seg. faults when you execute it? Or am I just missing something? You're accessing an array that hasn't been defined, that is a big "DUH!" in my book. It is interesting if it kills the compiler while trying to compile it, when it should be issuing a syntax error,
It's legal, although undefined, C. However, when appropriate, the compiler is allowed to issue a warning about accessing out of bounds data. This assumes the array has been statically or automatically allocated. The reason the compiler is crashing when parsing the expression is most likely a missing check determining whether (string literal + index) lies within the symbol table. One thing I have noticed in a gcc version that didn't crash, was that significantly large values for the index caused code to be generated that calculates the resulting 'char' value at runtime. 0x804831c <main+16>: mov $0xcafebabe,%eax 0x8048321 <main+21>: mov 0x80483f4(%eax),%al I would imagine gcc versions that crash do the above calculation at compile time.
not if the binary is executed. Hell, I have programs seg. fault all the time, no surprise there. Dale
