[Bug: 21.5-b32] Specifier crash in b32

The lisp backtrace and C backtrace are appended below. (Is there a

Whatever is convenient for you.
As you see here, the crash is induced by an assert, so that's our
fault, somehow. I'll see what I can do about fixing that.
`define-specifier-tag' is a user API; it shouldn't crash, ever.
define-specifier-tag(lo nil (lambda (charset) (string-match
"^lao" (symbol-name (charset-name charset)))))

On the other hand, whatever the code is that triggered the assert
doesn't seem to be in XEmacs or in our packages, based on grepping for
various key strings found in the Lisp backtrace. So you're going to
have to figure out what it is and fix it, because we will error on it
even if we don't crash.
