One further thought. Id the problem occuring in the code I posted, or in a modification or adaption of it?

To my knowledge, signal handlers will only work in the main thread, not in a subthread. If you have moved the signal handler into a subthread, that might explain the difference?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
