#10056: boost::promise runs arbitrary code while holding mutex lock
-----------------------------------------------+----------------------
Reporter: Jonathan Wakely <jwakely.boost@â¦> | Owner: anthonyw
Type: Bugs | Status: new
Milestone: To Be Determined | Component: thread
Version: Boost 1.54.0 | Severity: Problem
Keywords: |
-----------------------------------------------+----------------------
This deadlocks or aborts, depending on how pthreads handles re-locking a
mutex in the same thread:
{{{
#include <boost/thread/future.hpp>
struct X {
X() { }
X(const X&);
};
boost::unique_future<X> fut;
X::X(const X&) { fut.wait_for(boost::chrono::milliseconds(1)); }
int main()
{
boost::promise<X> p;
fut = p.get_future();
p.set_value( X() );
}
}}}
promise::set_value() owns a lock while invoking the copy constructor,
which might have side-effects.
