The crash location suggests a problem with a corrupted tuple, but it's
impossible to guess where the tuple came from.  In particular I can't
guess whether this reflects on-disk data corruption or some internal
bug.  Now that you have (some of) the query, can you put together a test
case?  Or try "select * from" each of the tables used in the query to
check for on-disk corruption.
