I meant to say that while Emacs does load loadup.el from source, it more
or less works normally after the load completes.

That shouldn't be a problem; none of the indicators in the resource
meter report more than 45% utilization when the crash occurs.

That is proving to be a problem.  MinGW flat out refuses to start, while
the GDB from ezwinports complains about "KERNEL32.DLL" missing the
symbol "AttachConsole".  Do you know how I can obtain a copy of GDB that
will still work on this old system?  Thanks in advance!
