The bug appears to be due to your Stepanov fix:
* toplev.c (rest_of_compilation): Remove dead code before
purge_addressof.
I wonder if Andreas's bootstrap failure is caused by this as well.
Unless we can track down the reason this patch is causing a
problem, it looks like GCC 3.0 will have bad C++ performance for this type
of code.
