[Bug middle-end/27173] [4.0 regression] ICE with -O -ftrapv

[reichelt at gcc dot gnu dot org]

------- Comment #4 from reichelt at gcc dot gnu dot org  2006-05-03 10:56 
-------
The testcase in comment #3 only crashes on x86_64-unknown-linux-gnu,
but not on i686-pc-linux-gnu.

The testcase below crashes on both archs:

===================================
char *p, *q;

inline int foo(int i)
{
  int j = (p - q) + i;
  return -j;
}

void bar()
{
  int n, i;

  for (n = 7; n-- > 0; )
    for (i = n; i-- > 0; )
      if (i)
        p += foo(i-1);
}
===================================
