Hello,

I havent found any relevant posts on this topic, so hoping the experts can 
rescue me.  My posts on p5p and ithreads didnt get any responses.

I'm extending Perl (with SWIG) and also embedding a cloned interpreter.  I use 
the cloned interpreter to invoke Perl sub's as callbacks.  The callback part is 
working fine.  However, a variable changed in the callback subroutine is NOT 
becoming available in the rest of the perl script.

I tried to "use threads:shared" and ":shared" the variable in question, but 
perl exits, complaining that another completely unrelated scalar is "Invalid 
value for shared scalar at".  

How can I "share" variable updates between the main perl script and the 
callbacks invokved thru the cloned interpreter?

I'm using v5.8.8 perl.  perl_clone() is using CLONEf_COPY_STACKS | 
CLONEf_KEEP_PTR_TABLE.  The perl sub is sv_dup() with the same flags in 
CLONE_PARAMS before call_sv().

Please see this post that describes my current code.
