ICE in a testcase, not sure about solution

[Paul Koning]

I'm running into an ICE in the GIMPLE phase, for gcc.c-torture/compile/386.c, 
on pdp11 -mint32.  That's an oddball where int is 32 bits (due to the flag) but 
Pmode is 16 bits (HImode).

The ICE message is:

../../gcc/gcc/testsuite/gcc.c-torture/compile/386.c: In function ‘main’:
../../gcc/gcc/testsuite/gcc.c-torture/compile/386.c:24:1: error: invalid types 
in nop conversion
 }
 ^
int
int *
b_3 = (int) &i;
during GIMPLE pass: einline
../../gcc/gcc/testsuite/gcc.c-torture/compile/386.c:24:1: internal compiler 
error: verify_gimple failed

The offending code snippet is (I think):

main ()
{
  int i;
  foobar (i, &i);
}


foobar (a, b)
{
  int c;

  c = a % b;
  a = a / b;
  return a + b;
}

where the foobar(i, &i) call passes an int* to a (defaulted) int function 
parameter.  Is there an assumption that sizeof (int*) >= sizeof(int)?

Any idea where to look?  It only shows up with -mint32; if int is 16 bits all 
is well.  I'm not used to my target breaking things before I even get to RTL...
