I get an ICE when bootstrapping the latest GCC on ia64-hp-hpux11.20.  It dies
when compiling adjust_field_type in gengtype.c.  Attached is a small test case
to reproduce the problem.  The test case only fails in ILP32 mode (the default),
it cannot be reproduced in LP64 mode (-mlp64) and it cannot be reproduced on
IA64 Linux because that has no ILP32 mode.

Test case:


void
adjust_field_type (int x)
{
  void *params[10];
  int i;
  for (i = 0; i < 10; i++)
    params[i] = ((void *)0);
  for (i = 0; i < 10; i++)
    if (x == 0) {
      if (params[i] != ((void *)0))
        foo (x);
    }
  return;
}
