I run all my tests with the --incremental flag, could this be causing what you're seeing? 

Another potential issue, I'm bjam seems to be crashing part way through each run. I've been meaning to do some digging into this, but haven't had the opportunity.  It crashes after msvc-11.0's pool test running valgrind (this test fails, but I think it is whatever is *next* that is causing the crash). Here's my whole bjam.log file if anyone is interested (8MB compressed): http://boost.teeks99.com/temp/bjam.log.zip

I'm mainly looking at teeks99-1a-win7-32on64, but this seems to be an issue with other Win32 testers as well, there's a failure here:

Which shows failures in test_arithmetic.cpp.

Now here's the thing, not only do I believe that bug has long since been fixed, but that file no longer exists in the repository as of rev #81654. There is a new test of the same name, but since the filenames all changed when I refactored the code I know there's something wrong here.  So while the tester appears to be testing rev #82100 I don't believe that to be the case.  BTW the Linux tests are cycling OK, and I see my changes taking effect there, but not on any of the Win32 tests.

Anyone any ideas here?

Many thanks, John.
