It seems to happen or not depending on which compiler I use to bootstrap. With 3.2.1 (binary from UCLA) and 2.9 (binary form IBM), I encounter the problem. With 2.95.3 (I bootstrapped), I do not encounter the problem. The fact that the problem can be reproduced with two different bootstrap compilers from such different releases leads me to suspect that perhaps there is some uninitialized variable involved. Or some other cause of undefined behavior. I don't know that much aboug gcc internals, but perhaps I can narrow down a little further somehow. But it will be time consuming and it would be good to know if anyone knows anything about this before I expend any energy on it.
