What version of Emacs doesn't set local-abbrev-table?  If I run
emacs-21.3 -q --no-site-file -f sh-mode, `C-h f local-abbrev-table'
displays

| Documentation:

And `M-: (eq local-abbrev-table (default-value 'local-abbrev-table))'
returns nil.

I guess the workaround for OP is something like:

(add-hook 'sh-mode-hook
           (lambda ()
             (or local-abbrev-table
                 (setq local-abbrev-table (make-abbrev-table)))))
