You can find and example in the C function custom_cmp from the Sort::Packed module (https://metacpan.org/source/SALVA/Sort-Packed-0.08/Packed.xs).

But passing the context around is done as an optimization in order to avoid calling Perl_get_context() repeatly. And it is not required unless the macro PERL_NO_GET_CONTEXT is defined. So, you are probably doing something on the wrong way.

The first thing that chokes me is that if you start from the Perl side, you shouldn't be calling perl_alloc at all.

Try remove any interpreter setup from your code, and calling some Perl function from the C side. It should just work.
