Hi,
I get Assertion failed timed_lock(::boost::detail::get_system_time_sentinel()), file c:\boost\thread\win32\basic_timed_mutex.hpp, line 64.
Code in basic_timed_mutex.hpp: void lock() {
BOOST_VERIFY(timed_lock(::boost::detail::get_system_time_sentinel())); //Line 64 }
That really is bizarre. Can you show a minimal example that demonstrates the problem?
Here is my code, i have marked where Assertion failed happends.
boost::mutex::scoped_lock lock(_mutex); while(_queue.empty()) { _condition.wait(lock); } //Assertion failed happends here. //Another thread is signaling the condition variable when an element is added to the _queue.
What is the lifetime of the various elements _mutex, _condition and _queue? Is it possible that they have been destroyed by another thread?
