This is "fixed" on the tuples branch.

Confirmed.  We do not create a EH region in the first place even though
fprintf and fputs could throw.  When CCP folds fputs to fputc it hits
the propagator assert

  if (tree_could_throw_p (new_stmt))
{
  eh_region = lookup_stmt_eh_region (stmt);
  /* We couldn't possibly turn a nothrow into a throw statement.  */
  gcc_assert (eh_region >= 0);

where /* We couldn't possibly turn a nothrow into a throw statement.  */ is
obviously only true if we'd have created a EH region in the first place.

So either that we didn't is a bug or the assert should be

   gcc_assert (eh_region >= 0 || tree_could_throw_p (stmt));
