Thanks for all the comments!

Apologies for typo in the code sample. I tried prefixing "our", but that didnt change the result.

As almut said, I am using a cloned interpreter and the perl sub/callback is executed in the cloned interpreter context. So, is the problem in how I'm cloning it? Or does cloning by definition mean, I cannot "share". Here is a post describing how I've done the embedding.

One "crude" way I can think of is to implement a "shared memory" API on C side to save/retrieve data between the subs and main. Perhaps CPAN has modules like this already..but I'm really hoping there is a more "natural" solution.
