I became a bit curious as to why two Lambda tests fail in the only release configuration for CW8.3, but don't fail in the debug tests. As seen in: http://www.meta-comm.com/engineering/boost-regression/developer/lambda.html And the really strange part is the lack of information from Boost.Test about it. It only outputs: Run output [2004-10-11 02:46:48 UTC]: **** no errors detected EXIT STATUS: 1 Which seems like a rather contradictory statement from the test system I don't really know what is going on here. But I've narrowed it down to some strange interaction when the "--" and "++" pre-ops are used. If I make the following changes the tests pass...
