I've written a callback function for an XS module designed to call a
perl function when invoked.
If I call the function directly, from within the C code, it runs through
completely as expected.
If its invoked as a callback from the library I am wrapping, it does
immediately at "dSP;" i.e. SV **sp = PL_stack_sp;
Specifically PL_stack_sp seems to cause SEGV when touched - I can't even
see the value, printf dies also.
I can't find anything similar discussed anywhere, does anyone have an
idea what might be happening?
