111614 of emacs-24 or of trunk?
By "looks regular" do you mean that you can reproduce it reliably?

Hmm... that terminates without error for me.

Could you look at log->next_free to see if it's a number or if it's nil?
If it's nil it means that Fremq somehow did not find `key', even though
we took it straight from the has-table itself.
If it's a number different from i, it means that Fremq somehow found
(and removed) another occurrence of `key' in the has-table.
Unless of course there's something trickier going on, such as some
signal triggering right between Fremq and the eassert (and that signal
somehow modifies the hash-table).
