Subject: [Bug c++/23383] New: builtin array operator new is not marked with malloc attribute
X-Bugzilla-Reason: CC
X-SW-Source: 2005-08/txt/msg01565.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

Testcase:
int f(void)
{
  int t;
  int *a = new int[1024];
  int *b = new int[1024];
  *a = 1;
  *b = 2;
  t = *a;
  delete a;
  delete b;
  return t;
}

the return is not turned into 1 but still have "return t" in the final_cleanup.
