[Bug middle-end/35041] New: ICE in tree-ssa-ccp.c with -fipa-struct-reorg

["alond at il dot ibm dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The following testcase fails for me when compiled with -O3 -fwhole-program
-fdump-ipa-all -combine -fipa-type-escape -fipa-struct-reorg

#include <stdlib.h>

typedef struct test_struct
{
  int a;
  int b;
} type_struct;

typedef type_struct **struct_pointer2;

struct_pointer2 str1;

int main()
{
  int i, j;

  str1 = malloc (2 * sizeof (type_struct*));

  for (i=0; i<=1; i++)
    str1[i] = malloc (2 * sizeof (type_struct));

  return 0;
}

The failure is:

try11.c: In function 'main':
try11.c:23: internal compiler error: in create_general_new_stmt, at
ipa-struct-reorg.c:1323
