I recently had this issue with sbcl and maxima: sbcl should be updated to 1.3.21 which caused an auto rebuild of maxima. Unfortunately sbcl<1.4 fails with glibc-2.26 (bug #640320). But still maxima was rebuilt, obviously for no good reason. (I had other examples in the past with even larger unnecessary rebuilds, but I don't remember them anymore). My request: If the causing package (here sbcl) for such an auto rebuild fails remove depending packages (maxima) from the queue. (I obviously use --keep-going as I run mixed stable/~arch and run updates when I am not at the computer).
