Hi, The following git repository (https://github.com/brads55/git-testcase) causes an assertion when running: $ git log --oneline --graph --all git-log: graph.c:1228: graph_output_collapsing_line: Assertion `graph->mapping[i - 3] == target' failed. The assertion seems to be caused by commit 0f0f389f12029b1c3745f8ed7aacfe6b2fc7a6cc. The graph structure of the above repository is as follows (as produced by v2.24.1): * a0a130c Merge commit '8f076d8' into HEAD |\ | | * f0f3be5 Merge commit '1b4b8d0' into HEAD | | |\ | | | * 1b4b8d0 6 | | * | 2c44f1b 2 | | | | * dd068b4 Merge commit '8f076d8' into HEAD | | | | |\ | |_|_|/ / |/| | | / | | |_|/ | |/| | | * | | 8f076d8 5 | | |/ | |/| * | | a261135 4 | |/ |/| * | a267dd6 1 |/ * 68f4772 0 Regards, Bradley Smith
