TAB autocompletion in dired producing error args-out-of-range

TAB autocompletion in dired producing error args-out-of-range

[Pankaj Jangid]

I have a file "a.txt". The directory is opened in dired. When I try to
rename it I press R over it and for autocompletion I press "a" and
<TAB>. I get the following error. Is this behaviour expected?

This is macOS build on today's commit

No, it's clearly not normal.

I suggest you M-x report-emacs-bug so we get a bug number to track it.
