Can you give a recipe for how to reproduce the bug, starting from
"emacs -Q"?

Yes:

1. emacs -Q
2. M-x edit-abbrevs
3. Scroll to last line - (global-abbrev-table)
4. Append: "dfn" 0 "definition"
5. C-c C-c (removes "modified" flag)
6. C-x k
7. M-x edit-abbrevs
8. Scroll down to last line - abbreviation is not there
9. C-x C-c (results in "Save abbrevs in ~/.emacs.d/abbrev_defs? (y or n) ")
10. "y" to above
11. Inspect .emacs.d/abbrev_defs - only contains one line:
    ;;-*-coding: utf-8;-*-
