An "internal compiler error" always indicates a compiler bug. Since you are using gcc 4.1.2 and the current version is 4.5.0, one obvious approach to avoiding the problem is to try a newer version of the compiler. If that is impossible for some reason, then other things to try would be to compile that bit of code without optimization, or to just try to adjust the code until the error no longer occurs. I would not be at all surprised if this error occurs when the compiler is trying to handle code which is itself erroneous, so you should convince yourself that your code is correct. Ian
