No, because it's not bjam thing. The Boost.Build testsuite does
include test/regression.py test that tests that non-zero
return from a program is detected. It worked on windows a couple
of weeks ago, and nothing was changed in that department since
then. Can you reproduce this problem using a minimal testcase --
preferrably not using any of boost.serialization, or any non-standard
assert functionality?

No. I plan to change regression tests to run those, however.
