1590	Coredump in load_bytecode when embedding	dukeleto		"I am trying to load P6object.pbc in PL/Parrot, but I get a coredump. This is happening in the 'security' branch of PL/Parrot:

http://github.com/leto/plparrot/tree/security

The function which is causing the coredump:
{{{
void plparrot_secure(Parrot_Interp interp)
{
    Parrot_PMC func_pmc;
    Parrot_String err;

    Parrot_load_bytecode(interp,""P6object.pbc"");
    func_pmc  = Parrot_compile_string(interp, create_string(""PIR""), PLPARROT_SECURE, &err);
    Parrot_ext_call(interp, func_pmc, ""P->"", interp);
}
}}}

This is Parrot r45974 on darwin/x86:
