The example the article gives isn't a general C problem, it's a common bug in some (mostly older) C/C++ compilers. As you point out GCC does not have this bug.

It's not a bug, it's intended to be undefined behavior; see http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html... (issue 1450)

Regardless of undefined behavior, it should not crash the compiler.

Ah, I missed that it can crash the tcc compiler. Yeah, that's a bug.

Probably easy to miss. One really does not expect the compiler to crash on code like that.
