So I've tried several things, but I'm still unable to figure out where the trace ends. It seems that the green values handed to the hook are for the start of the trace, which doesn't really help me with finding out where the trace aborts.

"operations" seems to be a list of trace operations. I tried printing .getarglist() off the last item in that list, but I'm not exactly sure what that data contains.

What I'm trying to get to is something that says "at a call to function X you tried to pass in a frame, now we have to force the frame". 

Any thoughts?

ABORT_ESCAPE means that the virtualizable was accessed from outside
the JIT during tracing. This is a big no-no, virtualizables are meant
to be used *only* from the JIT and not from the outside. If you look
at the trace up to that  point, it should be relatively obvious what's
happening (e.g. something is a call and not inlined). The trace is an
argument to the JIT hook.
