Please just post the stack trace to the list in future. We value
having that directly available from the archives.

It looks like the assertion failure happens at the point where the
next tuple is being compared to the current one, in respect of the
next tuple. The assertion failure occurs in the core code,
technically, though it is pretty much under the direct control of
amcheck at the time.

This means that my exotic explanation was wrong, and the actual
explanation is quite simple. (I told you that everyone makes stupid
mistakes.)
