return status of std::condition_variable wait_for is not always as expected

My application making use of a thread + timer to perform periodical operations in the background stopped working as expected when ported from native C++ (gnu c++) to web assembly.

Simply printing the status returned by

status = m_wait.wait_for(lock, ms);

i realised that from time to time it was 0 (no_timeout) when I expected a timeout.

Is that a possible bug?

Thanks

Start with the reported std::condition_variable::wait_for call, m_wait.wait_for(lock, ms), and compare its return status in native C++ and WebAssembly. Reproduce the periodic thread-and-timer behavior, then read the Threads and Atomics proposal sections covering condition-variable waits. Done means determining whether the no_timeout result violates the expected semantics and documenting a minimal reproduction or confirmed specification issue.
