This is indeed a problem caused by the copy op. Examining the code in src/ops/set.ops we see that VTABLE_destroy(interp, $1) is called, which in turn calls mem_sys_free(PMC_data(pmc)). Thus, the PMC_data, which is the actual "object guts" has been freed before the call to VTABLE_morph(interp, $1, type). This calls the generic object morph function, which uses the aforementioned guts to dispatch to the appropriate class function - oops! As a workaround for now, I suggest commenting out the call to VTABLE_destroy, which will cause memory leaks but not segfaults. I will work on a proper solution later tonight if nobody beats me to it.
