Digging means:
run git bisect and report the commit.
And this makes the compiler happy:
  Revert "tree-diff: catch integer overflow in combine_diff_path allocation"

    This reverts commit 5b442c4f2723211ce0d862571e88ee206bfd51bf.

Test suite passes,
( except t9115, the 2 new test cases "svn.pathnameencoding=cp932".
  More info about that later)
