I still cannot reproduce this bug with a newer compiler:
gcc version 3.5.0 20040908 (experimental)
so I can't confirm it right now.
Notice that the code is not valid C++ (breaks aliasing rules with the cast), so
either you specify -fno-strict-aliasing while building (at least) this file, or
you could hit wrong-code generation and all kind of side-effect.
Anyway, this is still a valid report, as we should not emit an internal error
under any circumstances.
