So, IIUC the symbol-function slot of the clear-transient-map symbol
points in the middle of a vector?
Since the symbol-function slot of the clear-transient-map symbol is only
set once, I think this means that the vector to which it pointed has
been somehow freed.
Of course that shouldn't be possible: at any previous GC, either the
clear-transient-map symbol was found live and traced (so the vector to
which it pointed shouldn't have been freed) or it wasn't found live, in
which case the symbol-function slot should have been set to the special
"dead" value.
