I spoke too soon.

Your patch fixes the problem, but I now I'm seeing an assertion
failure when writing some files (most notably, ChangeLogs). That is
100% repeatable: I try to write src/ChangeLog, for example, and get
the assertion failure every time.

The CHAR_TABLE_P call at the start of char_table_ref is getting a null `table'.

See the attached debug trace at the point where `table' is Qnil.
