I'm not following completely..so, I'm glad you are able to talk me through it. Also, I'll have to try the "caching the context" idea tomorrow.

When your C/XS code receives the callback address from Perl, take a copy of the *current* context and save it away in a suitable place.

At this point, my script is just a single line of execution (no ithreads or anything else), except for the subs that are the callacks. So, can there still be more than one context when I get the callback address in XS?

With the "force context" solution, I encountered a crash (actually a "Not a CODE ref" assert) in a scenario when a 2nd callback was called from a 2nd thread. I was puzzled at that..but, perhaps perl.exe has more than one 'context' by default? Or perhaps its because I didnt "save" & "restore" contexts after the 1st callback that the context for the 2nd is messed up?
