Hi E. Pasma,

Thanks for your interest in this! The test case failed on trunk, after the
previous bug that you are referring to was fixed. It seems that the bug I
newly reported has been fixed in
https://www.sqlite.org/src/info/ebe4845cd0ffb96b. In order to trigger it,
this more complex (and admittedly obscure) test case was necessary.

Best,
Manuel
