John Maddock has just added the tests to trunk/libs/config that I wrote for a new defect macro: BOOST_NO_COMPLETE_VALUE_INITIALIZATION
A test failure indicates that the specific compiler doesn't have completely implemented value-initialization.
BTW, the test code itself is at https://svn.boost.org/svn/boost/trunk/libs/config/test/boost_no_com_value_in... It tries to value-initialize various types of objects, and returns the number of detected initialization failures. John has already looked at the code, but if you also have any comment, please let me know. FYI, I assigned a ticket to myself to define the new defect macro for any compiler that has failures on this specific test at the Boost Config regression page: https://svn.boost.org/trac/boost/ticket/4080 Kind regards, Niels -- Niels Dekker http://www.xs4all.nl/~nd/dekkerware Scientific programmer at LKEB, Leiden University Medical Center
