,----
| abbrev-file-name is a variable defined in ‘abbrev.el’.
| Its value is ".abbrev_defs"
| Original value was 
| "/home/oub/.abbrev_defs"
| 
|   You can customize this variable.
| 
| Documentation:
| Default name of file from which to read abbrevs.

The default value .abbrev_defs seems odd to me shouldn't it per default
be
"~/.abbrev_defs" at least for Unix/BSD dialects and MacOS?

But the point is. If I use the vanilla abbrev file from master I don't
get an error, with your patched version I do, but I think I know what's
up, I had some old abbrev.el file somewhere in my load path. Because
with abbrev vanilla from emacs master, my abbrevs are not loaded.
I check that and re try your patched version later (I still struggle
with flyspells abbrev mechanism).
