By the way (should have written this a long time ago): My experience with
things like this is that you should probably save all the snippets you create,
even if they didn't crash the compiler in any interesting way (i.e. worked
just fine). If we ever want to have a comprehensive testsuite, then these
are the pieces that you would want in there.

Of course, getting the gcc folks to accept a thousand small programs that
just test small parts of the language is going to be harder than proposing
a single testcase that shows that a particular patch fixed a particular bug,
but I think it would be worth while.

(For example, if we had had testcases that had stresses static template
members in all their aspects, we would have had a dozen or so regression
reports less lately... :-)
