[Israel.pm] Counting my scalars

Hello There.

I solved my own problem. What triggered the error was:
unsigned char value = SvTRUE(POPs);

I changed it with POPi and everything worked. (donno why... :-( )

Anyway, now I'm playing with my favorite embedding-perl, and getting:
Attempt to free unreferenced scalar: SV 0x3fece4 during global

Can anyone tell me how do I inspect the scalars that are left?
