Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2013-06-18 Ever confirmed|0 |1 --- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> --- The timed mutex requirements [thread.timedmutex.requirements] say: The expression m.try_lock_until(abs_time) shall be well-formed and have the following semantics: Requires: If m is of type std::timed_mutex, the calling thread does not own the mutex. Anyway, confirming as there's a bug here relating to clocks with different epochs, but it's easy enough to fix, I can look into it. The same problem exists with the private mutex type defined in std::shared_mutex
