On some compilers some of my SFINAE-related "convert" regression tests fail. So, I tried to update status/explicit-failures-markup.xml to explicitly mark those test failures rather than masking/disabling them. For understandable reasons I have no permissions to modify the file, so that update of mine was denied. I tried contacting Daniel James as he often helps me with build matters but he is seemingly unavailable. I am hoping someone else might have edit-permissions to the file and be kind enough to add the following code (below) to the file for me? My apologies for such a wide post or if my request is misdirected. Your help in the matter is much appreciated. Thanks, Vladimir. <!-- convert--> <library name="convert"> <test name="convert_test_has_begin"> <mark-failure> <toolset name="msvc-8.0*"/> <toolset name="msvc-9.0*"/> <toolset name="msvc-10.0*"/> <toolset name="msvc-11.0*"/> <note author="Vladimir Batov"> The relevant SFINAE support is broken in MSVC up to version 11. </note> </mark-failure> </test> </library>
