Comment(by plobsing):
Here's what's happening (AFAICT):
* The exception (segfault, ParrotInterp.elements not impl, etc...) is
happening because ADD_OP_VAR_PART() in
src/pmc/sub.c:Parrot_Sub_get_line_from_pc is looking at bogus bytecode.
* This is happening in the profiling runcore code *after* the returncc
from runtime/parrot/library/P6object.pir:onload.
* The bogus bytecode is comming from a bogus context set up by
load_bytecode. This comes from r41115 as a fix for TT #150.
Here's how one might fix the problem:
* figure out how to denote and detect bogus contexts and ignore them
properly in introspection code
OR
* figure out how to avoid using bogus contexts
