If the program

__complex__ double f (__complex__ double x, double y) {
  try {
    return x / y;
  } catch (char *s) {
    return x;
  }
}
----------------------
is compiled with "cc1plus bug.cc -fnon-call-exceptions", it fails with the
error:

Note this is most likely a regression from 3.4.0.

Though -fnon-call-exceptions really is only heavily used in java and java does
not use complex types.

It is heavily used in Ada as well, but Ada doesn't use complex types either.
