Ok, I think this is resolved now. The crash turned out to be happening
during the Boost.Build tests which are run separately from the main
regression tests. The 'default-bjam' setting that was specified here
caused the system to find an ancient copy of bjam that was installed
elsewhere on the regression test machine (rather than the new one that
it built). Because it was using this ancient bjam to run the
Boost.Build tests, it was crashing. I update this bjam executable to a
new one and now everything is running smoothly.
