functional/hash, numeric/interval and regex are the libraries with regressions.
There's something strange going on here: Math lib: mpfr_concept_check and ntl_concept_check are marked up in expected_failures.xml (and have been since they were added - they rely on external third party software to pass), but are still being shown as regressions. test_hypergeometric_dist2 and test_hypergeometric_dist3 are failing due to internal compiler errors in msvc-8, but strangely they compile just fine locally. I don't really see what I can do here... Regex lib: regex_timer is failing on two platforms (including vc-8) but works fine here, and in any case there are no pertinent changes as far as I can tell. The program output here: http://tinyurl.com/yzm2xpm suggests it ran OK to completion, and yet it's still marked as failing, is the full build log available somewhere? TR1/type_traits Libs: Failures form vc7.1 and things that aren't supported with that compiler - it's possible that they're work-round-able, but will mark up for now. John.
