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.hu...@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:
