Reduced testcase:

static int spready[] = {
};
void explosion_map (int y)
{
  for (int i = 0; i  4; i++)
if (y * spready[i]  0)
  break;
}
void explosion (void)
{
  explosion_map (0);
  for (int i = 0; i  2; i++)
continue;
}

Confirmed.  We enter with the unfolded tree

  D.2472_4 * 00

which is propagated from

  D.2473_6 = D.2472_4 * 0

during forwprop.  inlining is not properly folding its trees during inlining
of explosion_map (0).

I know what this issue is.  This is most likely the same issue as PR 30564,
which I need to get around to fixing still.

And it is the same as my patch fixes the problem also so closing as a dup.
