Hello list,
I asked a question over at superuser.com about git checkouts messing up the execution bit of freshly committed files:
http://superuser.com/questions/204757
To put it in a nutshell: I edit and commit a file in branch "master", then I check out branch "dev" and the edited file gets the execution bit set. This leads to a working copy differing from the content of the index. It's especially painful when I try to merge "master" into "dev", which fails then. I'm working under ext4 and Samba/CIFS, respectively.
One answerer at superuser thinks that this looks like a bug in git itself. Therefore I'd like to check with you, if there is possibly another explanation for my observation, before I issue a bug report.
Best, Manuel
