Hello,

I have tried using 'git bugreport' but could not figure out how to edit text in the console and send report, so I'm just reusing that form in this email. Let me know if any other information is needed.

What did you do before the bug happened? Ran the following commands: git checkout mybranch git merge master git mergetool

What did you expect to happen? I expected git to open my configured mergetool

What happened instead? It fails with message "merge of myfile.cs failed"

What's different between what you expected and what actually happened? Merge does not work.

Anything else you want to add: This issue started to happen since git version 2.29.0. Earlier versions work as expected.

.gitconfig:
[core]
     editor = \"C:\\Microsoft VS Code\\Code.exe\" --wait
[user]
     name = myname
     email = myemail
[fetch]
     prune = true
[pull]
     rebase = true
[diff]
     tool = bc4
[merge]
     tool = bc4
[difftool "bc4"]
     cmd = \"c:\\Program Files\\Beyond Compare 4\\bcomp.exe\" $LOCAL $REMOTE
     trustExitCode = true
[mergetool "bc4"]
     cmd = \"c:\\Program Files\\Beyond Compare 4\\bcomp.exe\" $LOCAL 
$REMOTE $BASE $MERGED
     trustExitCode = true

I believe that this is fixed as per https://github.com/gitgitgadget/git/pull/787. It has also been merged into Git for Windows' `main` branch via https://github.com/git-for-windows/git/pull/2899. This means that it should be fixed in the latest snapshot: https://wingit.blob.core.windows.net/files/index.html

Ciao, Johannes
