Have you done that?

I get the same here, also with GCC 4.6.0, but not with 4.7 [180524] so
_may_ already be fixed in AdaCore's sources.

When you see a bug box like this, it's definitely a compiler error;
whether it's because it doesn't handle your legal code, or because it
fails to detect your illegal code and give a proper error report, it's
still wrong!
