• If the problem was occurring with a specific repository, can you provide the

sorry,it's not a public repository

Sorry, then there is little I can do. You could try to recreate a real MCVE (git svn clone does not even work, let alone reproduce the issue you described).

This bug is very likely to be data shape dependent.

Since there is not enough information to act on, the only thing I can do is close this unresolved.
