5682,BOOST_TEST_REPORT_LEVEL and BOOST_TEST_LOG_LEVEL crash on Mac OS X with g++ 4.6.1,Thomas Krennwallner <tkren@…>,Gennadiy Rozental,"Using the environment setting {{{BOOST_TEST_REPORT_LEVEL=detailed}}} and {{{BOOST_TEST_LOG_LEVEL=all}}} frees an unallocated pointer on mac os x when running simple boost unit tests compiled with g++ 4.6.1; standard g++ 4.2.1 has not this problem:

{{{

Compiling with g++ 4.6.1 gives

A backtrace does not give too much information:
