No, not fixed in 26.1, where this depends on some context.
This is rather random, but here's a way to reproduce the
bug in Debian:

1. emacs-gtk -Q foo.c
   (where foo.c does not exist)

2. Paste "// Comments are good (aren't they?)"

3. Type C-M-p

I get an error:

forward-list: Scan error: "Unbalanced parentheses", 35, 1

This problem does not occur without the apostrophe.
