In this testcase you don't have foo being transformed to void function:

gcc malloc.c -c -O2 -fdump-tree-optimized=/dev/stdout

;; Function foo (foo, funcdef_no=0, decl_uid=1913, cgraph_uid=1,
symbol_order=0) (executed once)

__attribute__((noinline, malloc))
foo (const char * p)
{
  void * _4;

  <bb 2> [local count: 1073741824]:
  _4 = bar (p_2(D)); [tail call]
  return _4;

}
