!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.

Repeatable ICEs

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.

Work around: Recompiling at a lower optimisation level will frequently avoid the ICE and allow your compilation to proceed.

Random ICEs due to hardware problems

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.
