A bisect like that is not likely to converge in any reasonable time, given =
the
stochastic nature of those crashes.

While the mean-time-between-driver-crashes is dramatically different, there
will be occasions on which 4.13 will crash early enough to yield a false &q=
uot;bad",
and there will be occasions on which 4.17 is lasting like the 20 minutes or=
 so
to assume a false "good".

What about the multitude of debug-options - isn't there one that could allow
for some more insight on when/why the driver crashes?
