Hi, I've noted that tuple_test_bench is marked as a regression for BCB 564: http://tinyurl.com/62plc However, in the the following page listing Boost 1.31 issues, this test seems to appear as a failure: http://tinyurl.com/6j68r The problem seems to be related with BCB having a hard time with specializations on const types. So my questions are: 1. Is this really a regression or an expected failure as it seems to be present back in Boost 1.31? 2. Scanning the list, some folks claim that the problem goes away with BCB 5.6.4, yet what we have have does not indicate so. Anyone knows the status of this problem wrt to the version of the Borland compiler? 3. tuple already has an alternative implementation for those compilers without PTS, driven by BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION (line 26 of boost/tuple/tuple.hpp). Could someone with local access to the Borland compiler try to apply the alternative implementation by replacing that line with the following? #if defined(BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION)|| defined(BOOST_BCB_PARTIAL_SPECIALIZATION_BUG) (I don't know if BOOST_BCB_PARTIAL_SPECIALIZATION_BUG really relates to this particular problem, but its name fits perfectly well.)
