OK, your code may slightly diverged from CVS right now...

That's not so old, I think. As you see, I still use 2.95.3 and it is
just a bug fix version from yours. When we can integrate your code
and CVS trunk, I hope we will check again for this issue.

The problem this time is not directly related to assertion itself.
My observation is it is a side effect produced by optimization.

For linux, I use Mac. And I still keep one Sun-3/260 for NetBSD but
it is noisy and becomes so hot while running.
