    I just got this one when T was GCing.

    ** Error: you shouldn't try to GC with a fault frame on the stack.
      You probably won't be able to (RET), so try (RESET).

It is a known bug that if a GC happens while you're in the dynamic
context of certain kinds of errors (like wrong number of args) or
interrupts (like ^Q/^C) then the GC may not be able to scan that part of
the stack correctly.  Your T should be be fine except that certain stack
frames might be screwed up, so when you get this it's a good idea to
(RESET).
