5615,BOOST_CHECK_EQUAL does not work well with const static members,anonymous,Gennadiy Rozental,"I have tried to create set of test cases using BOOST_AUTO_TEST_CASE_TEMPLATE() macro. Each tested class shares the same interface, but values returned from functions are different. Therefore I decided to use helper traits template to avoid code duplication. Each traits struct contains arguments and expected results for tested classes, stored as static const values - see example below. Unfortunately this code does not link successfully - linker complains about missing static struct members. Fortunately workaround is simple - just copy expected value to temporary variable and use it in BOOST_CHECK_EQUAL().

Please fix this to allow this code to compile and link successfully, without using workaround.
