[Bug c/18814] New: Incorrect reinitialization of compound literal

["austern at apple dot com" <gcc-bugzilla at gcc dot gnu dot org>]

According to the ISO C standard, compound literals in functions are objects with automatic storage 
duration.  The following test case modified such an object, so in this test case the value should be 1 the 
first time through the loop and 77 the second time.  Instead we see 1 the first time.
#include <stdio.h>

int main() {
  int i = 0;
  int* p;
top:
  p = &((int) {1});
  printf("%p %d\n", p, *p);
  *p = 77;
  if (i++ == 0) goto top;
  return 0;
}
