bug#59507: 29.0.50; Autoloads generation hangs on Windows and Emacs 29

[Denys Mentiei]

Hello!

 

It looks like "loaddefs-generate--file-load-name" hangs when it receives

a path starting with "c:/".

 

Looking at the code, it seems like the very first loop, which

eats the path piece by piece with (file-name-directory name) never

terminates as (file-name-directory-name "c:/") returns "c:/".

 

In GNU Emacs 29.0.50 (build 1, x86_64-w64-mingw32)
