            Bug ID: 67408
           Summary: <mutex> assumes that __gthread_mutex_t
                    and__gthread_recursive_mutex_t are the same types
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: sebastian.huber@embedded-brains.de
  Target Milestone: ---

The problem is in in:

[...]
#if _GTHREAD_USE_MUTEX_TIMEDLOCK
  template<typename _Derived>
    class __timed_mutex_impl
    {
[...]
          auto __mutex = static_cast<_Derived*>(this)->native_handle();
          return !__gthread_mutex_timedlock(__mutex, &__ts);

Here I get this for example:
