Your XS DLL and perl core do not agree on -D options=2C or the config.h fil=
es used to compile both are different. Perl XS DLLs/SOs are not binary comp=
atible with anything but the perl binary that built them. The high 16 bits =
of the handshake key are the size of the interp struct. Your XS module and =
perl core do NOT agree on where the memory offsets for various members in t=
he interp struct are.=0A=
