Kyle,

Are you trying to set a handler for a signal somewhere in your code?
If so, it's unlikely to work.  In general signals and threads don't
play together well.  A bit of googling will show you the mine field.

If you're trying to catch a std::exception, that should work fine.

Hi Eric

I did not set any handler except 'except KeyboardInterrupt: ...'

I tried it on Ubuntu as well which turned out to fail.

Yes, I agree with you that it's likely the problem of coworking of signals and threads.

I tried a single threaded program where the same mechanism did work.

So I will change my approach completely.

Thanks for making things clarified.
