runs perfectly here!

You must be kidding..Holy cow! Indeed, where does it leave us know..

Guess, it could be platform-dependent stuff. I'll definitely need to get a demonstration of the problem first. I'd have to learn Inline to get rid of the compile errors (about "CALLBACK" and also that "thread(1|2) are undefined)...or revise the example from my earlier posts. I may pick the latter approach.

I completely understand your "warnings" on how much you could help, but I feel you will still be quite helpful. So, let me describe a bit more of the project, anyhow.

We are on *nix platforms (ubuntu and fedora mainly but RH too). The 'arch' is client-server : a standalone executable server (all C). A client-lib (all C) that I've wrapped with SWIG. An application (perl script, in our case) uses the clientlib API to exercise server functionality. Client-server communicate via sockets. Client API spawns threads and sends msgs to server to 'do things'. Server program will use some HW to do its work. When done, server sendsback msgs, results via the socket. The threads will then call the approriate CCBs based on various msgs received from server. Make sense? I hope :-)

Which means that the CCB will be invoked not in a new, clean thread, but rather in an existing (Perl created) thread, via a longjump

As in the sample code we exchanged, in my real project too, the threads are created on the C side and not by Perl. So, it seems this italisized statement would not apply, right?
