A binary search (with "git bisect") did not work out too well, so I wrote a script which iterates over the latest commits with a linear search (the script misc/checkout-latest-good-commit).  This allowed me to find (after trying 20 commits in 40 minutes) that the bug was introduced in commit c89610066937d51eeeac866bb6320bcd5bd61f87 when "long" (a signed integer) was changed to "size_t" (an unsigned integer).  So I have pushed a commit which reverts this back until I can investigate further and see which one of the uses of a signed integer were really required.
