I've been looking at your regression test results for mingw:
config_test and all the regex tests are failing with a runtime exit code of 128, however they pass for me here, and for some of the other testers as well (see the Bronek Kozicki results). Do you have any idea what's happening here? If you can get a stack backtrace for the problem that's happening in config_test that would be a big help.
I re-compiled the test (config) using dev-cpp (which is the mingw I'm using) and ran the test manually AND with the debugger error_count (and what gets returned) is clearly 0 in both runs.
apparently there is some hiccup w/ the interface to the boost test fixture. I'll be happy to debug there if someone can give me a hint where to start.
Not sure, but you could try: bjam -a -d2 config_test which may indicate some kind of difference between what bjam is doing, and what your manual builds are doing; then again it may not :-( Thanks! John.
