Dave, Dominique,

As I have no such execution failures on any one of machines, would you please
help me debugging the execution failures?

I am actually need the place where it fails and assembly files. The most
convenient file is wo_prof_mult_fields_peeling.c . Can you please produce an
assembly for it? For this file I also generated the artificial result of
struct-reorg optimization (below), to be compiled without -fipa-struct-reorg,
but with all other flags (-O3 -fdump-ipa-all -fwhole-program -combine
-fipa-type-escape). The idea is to compare two assembly files, from original
wo_prof_mult_fields_peeling.c and from faked one:

#include <stdlib.h>
#include <stdio.h>
typedef struct
{
  int a;
}str_t0;

typedef struct
{
  float b;
}str_t1;

typedef struct
{
  int c;
}str_t2;

typedef struct
{
  float d;
}str_t3;

#define N 100

int 
main ()
{
  int i;
  str_t0 *p0 = malloc (N * sizeof (str_t0));
  str_t1 *p1 = malloc (N * sizeof (str_t1));
  str_t0 *p2 = malloc (N * sizeof (str_t2));
  str_t0 *p3 = malloc (N * sizeof (str_t3));

  for (i = 0; i < N; i++)
    p0[i].a = 5;

  for (i = 0; i < N; i++)
    if (p0[i].a != 5)      
      abort ();

  return 0;
}

Thank you,
Olga
