You haven't provided most of the information requested at
http://gcc.gnu.org/bugs/

The code has undefined behaviour, that doesn't mean you get an error, it means
the code is buggy.

It's not the compiler's job to diagnose it. On GNU/Linux use valgrind or
glibc's MALLOC_CHECK_ feature (see 'man malloc')
