Hello,

I didn't compile my own version from sources, I wrote that it was probably after 'zf/subtree-split-fix', because it was related to subtree split.

And I managed to find out by trying that the change happened after version 2.43.0 and was included in version 2.44.0-rc0, so i assumed that.

Go on and try same split with 2.43.0.
