Indeed.
I'm sure every semi-involved Wine developer can imagine dozens of
"reasons of the day" why winedbg doesn't launch properly on error again...
Failure in wine exception handling code, failure to look up winedbg
(both registry and disk), failure to pass winedbg cmdline parameters properly,
failure to get winedbg started up properly, failure to get winedbg to
parse the current modules and stack frame properly, ...

That's why a "no frills" debugging mechanism is a good idea IMHO.

P.S.: no offense to Eric. He's done TONS of very useful things to winedbg,
and when considering how many fatal architecture changes winedbg had
to go through, it's amazing that it still works pretty well. :-)
