           Product: gcc

I found this bug after a NULL pointer dereference:

// test.cpp
int main() {
  return (new char[8010463299950541741]) != 0;
}


$ g++-4.8.1 -fsanitize=address test.cpp -o test && ./test ; echo $?
==7913== WARNING: AddressSanitizer failed to allocate 0x6f2ae1ee17dafbad bytes
0


$ g++-4.8.1 test.cpp -o test && ./test ; echo $?
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
