In GNU Emacs 19.25.93.1 (sparc-sun-sunos4.1.3) of Tue Aug  9 1994 on wotan.ai

I decided to debug this further:

One problem is that line 75 of paren does not check if matching-paren returns
nil before attempting a numeric not equals test.
nil is a valid return value for this function.

Here is the surrounding code:
		(if pos
		    (let ((beg (min pos oldpos)) (end (max pos oldpos)))
		      (and (/= (char-syntax (char-after beg)) ?\$)
			   (setq mismatch
				 (/= (char-after (1- end))
				     (matching-paren (char-after beg)))))))
