I have a reduced testcase down to around 160 lines, still reducing.

Confirmed, reduced testcase (20 lines :) ):
typedef struct edge_def { long long probability, count; } *edge;
typedef struct VEC_edge { unsigned num; edge *vec; } VEC_edge;
edge make_edge (void);
static inline edge
ei_safe_edge1 (VEC_edge *container, unsigned index)
{
  if (index != (container)->num)
    return (container)->vec[index];
  return 0;
}
void construct_exit_block (VEC_edge *preds)
{
  unsigned index;
  edge e = make_edge ();
  e->count = 0;
  for (index = 0; ei_safe_edge1 (preds, index); index++)
    ;
  e->count = 0;
}

> Confirmed, reduced testcase (20 lines :) ):
One more thing, the options to reproduce this with a normaly compiled compiler:
-march=pentium3 -O1 -m32
