OK, the only thing that I can think of at present that could lead to
this is an incomplete setjmp flush of the registers to the C stack.  I
know we went around on this before, but then I dropped this line of
reasoning when it looked possible that your FIND_INIT fix would clear
all 4 of the then outstanding problems, when it actually cleared 2
(correct?).   In any case, I suggest we postpone further work on this
in favor of getting gcc-3.3.3 to work if this is at all feasible.
This is the single issue now standing in the way of 2.6.2.  If it
becomes protracted, we may cave in and move on, but I think its worth
investigating in case a quick fix might present itself.

Might David Billinghurst also lend a hand?
