!Why does gcc give _internal error_ messages?

If you see diagnostic messages like

../include/wx/ctrlsub.h:156: internal error: Segmentation fault

then try running the same compile command again.

Some _internal error_ messages really are defects in the compiler. If you have a reproducible test case, then mention it on the mailing list. Others may know about your problem already and be able to help.

But if you see random _internal error_ messages that go away when you recompile the same code, then it's almost certainly a hardware problem. This page http://www.bitwizard.nl/sig11/ explains why that's the case even if gcc is the only program that commonly has this problem.
