C++ "deque iterator not dereferencable" multithreading. WaitForSingleObject() lets the thread through

When im calling WaitForSingleObject() in my Pop() function even if the event notempty is NOT set it doesnt stop it, i dont know what to do with it. it should wait for a number to be pushed, and even if it is not pushed, it should still wait for an INFINITE amount of time.

same when calling WaitForSingleObject() in Push() when the event notfull is NOT set.

working in Microsoft VS RC 2017 with character set not set.

I dont know how to get this working (waiting for infinite time to push/pop something).

Your calls to WaitForSingleObject are using INFINITY for the timeout parameter, and instead should be using INFINITE.
