This sounds like the build actually starts (i.e. the testing tools are built
successfully and library tests began running, some of them failing). This is
not the problem we're seeing, but it would be interesting to know why it
doesn't manifest in your case.

Did you somehow modify your build scripts? Do you manually invoke 'b2 headers'
before starting tests? Do you delete the boost directory before running tests?
Is there anything special in your user-config.jam? How do you start tests?

There's clearly some difference between testers, which makes some of them fail
and others succeed.

I'm not a Boost.Build expert so I didn't quite understand your way of fixing
it. Could you specify how and what code you changed (i.e. a patch or modified
code sample)?
