Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID --- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> 2012-11-02 04:08:25 UTC --- >For example, passing a virtual address 0x00001000 and c = 0x80000000 to the function should actually run over the address range 0x00001000 .. 0x80001000, No it runs over the address range 0x00001000 .. -1 and more as 0x80000000 * 4 wraps/overflows. If x was char* then I would say there is a bug but this is int* which has a size of 4.
