The following summarizes the regression test status of each of the Boost libraries. We're doing well, but there are still quite a few libraries with outstanding failures. I've listed those libraries here along with the compilers/platforms on which they are failing. May is half-way finished: I hope to stabilize by the end of the month for release. Lots of failures: iostreams (vc-7_1, vc-8_0, mingw-3_4_2, borland-5_6_4, gcc-3_3-darwin, gcc-2.95.3-linux, gcc-2.95.3-stlport-4.5.3-linux, gcc-3.3.5-linux, gcc-3.4.3-linux, intel-8.1-linux). numeric/ublas (all compilers fail test4, test5) parameter (vc-7_1, borland-5_6_4, cw-8_3, msvc-stlport, vc7, msvc, gcc-2.95.3-linux, gcc-2.95.3-stlport-4.5.3-linux) program_options (borland-5_6_4, vc7, gcc-3_3-darwin, intel-8.1-linux) ptr_container (borland-5_6_4, cw-8_3, msvc-stlport, vc7, msvc, gcc-2.95.3-linux, gcc-2.95.3-stlport-4.5.3-linux, vcc-3.4.3-linux) range (vc-7_1, vc-8_0, borland-5_6_4, gcc-2.95.3-linux, gcc-2.95.3-stlport-4.5.3-linux, gcc-3.3.5-linux, gcc-3.4.3-linux) serialization (most compilers fail something) test (every compiler fails something) A few failures: algorithm/string (vc7, cw-8.3) date_time graph (vc-8_0) integer (msvc) iterator (borland-5_6_4) math (cw-9_4) multi_index (msvc) pool (borland-5_6_4) python (vc-8_0, msvc-stlport, vc7, gcc-3_3-darwin) random (gcc-3_3-darwin, gcc-2.95.3-linux, gcc-2.95.3-stlport-4.5.3-linux) regex (borland-5_6_4, msvc-stlport, vc7, msvc, gcc-2.95.3, gcc-2.95.3-stlport-4.5.3-linux) spirit (cw-8_3, gcc-3_3-darwin on multiprocessor machines) thread (cw-9_4, msvc-stlport, msvc) utility (call_traits_test on msvc-stlport, vc7, msvc) wave (cw-8_3) Libraries that with no failures: algorithm/minmax any array assign bind concept_check config conversion crc disjoint_sets filesystem format function functional functional/hash io lambda logic math mpl multiarray numeric/conversion numeric/interval optional preprocessor rational signals smart_ptr static_assert timer tokenizer tuple type_traits variant Doug
