`dynamic atexit destructor for 'threadPool' #35

Closed lawabider closed 3 years ago

lawabider commented 3 years ago

I'm getting a weird exception / crash at end of runtime.

This console program produces it:

#include <RStein.AsyncCpp/Tasks/TaskCompletionSource.h>

int main()
{
        RStein::AsyncCpp::Tasks::TaskCompletionSource<__int64> _tCS;
}

I had never heard of atexit() before this, and it was quite confusing. Should I ignore this crashing? Is there a work-around?

Here is the call stack for the above:

Hi @lawabider , what version of the library do you use? Current master branch, VS 2010, Release/Debug X64 configuration.

My console application.

#include "../RStein.AsyncCpp/Tasks/TaskCompletionSource.h"
int main()
{
        RStein::AsyncCpp::Tasks::TaskCompletionSource<__int64> _tCS;
}

Result. image

Thanks; I've downloaded the code again and it's working now.
