An ICE is always an error in the compiler, even if there is also an error
  in the code.

Please do.

The gcc maintainers cannot do much without the preprocessed sources; not
  everyone has STLport-4.0, and even if they do, the contents of <iosfwd>
  mostly like vary depending on the configuration. Without knowing what is
  in <iosfwd> it is very hard to determine the nature of the bug.

So when you report bugs, please include pre-proceessed sources (obtained
  with g++ --save-temps, again, see the bug reporting instructions.)

Thank you for your bug report.
