Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID --- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-07-13 09:38:45 UTC --- 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')
