I myself don't see the problem, but according to the report from
David, some keymap seems to be clobbered.

I meant a kind of analysis to ensure that any literals inside a
function are not modified. In dynamic scoping environment, objects
exposed to another function are not limited to those are passed via
arguments.

To detect the case that the contents of the pure storage are changed
accidentally. It actually occurred when I tried preloading
international/encoded-kb.elc. Maybe CHECK_IMPURE should be added to
Fccl_execute_on_string?
