Thanks for reporting that you are affected as well.  Regarding your question
about bumping the priority, one problem for the TM support in general has been
to be able to judge how many users are out there, and whether they are
interested in TM for in-production software or just toying around with it
because it's something new.  This holds for GCC's implementation, but also for
the ISO C++ TM Technical Specification.

Thus, if you or anyone else is interested in using TM for real, please share
your feedback with me personally or ISO C++ Study Group 5
(https://groups.google.com/a/isocpp.org/forum/?fromgroups#!forum/tm ; sending
email to tm@isocpp.org might work even if you're not subscribed to this list,
or it should at least end up in a moderation queue).  Sharing your feedback
will help us and Study Group 5.
