#1293: eq?-hash tables calculcate different value for objects after they're
mutated and lose locatives after GC

  Reporter:  sjamaan         |      Owner:
      Type:  defect          |     Status:  new
  Priority:  critical        |  Milestone:  4.12.0
 Component:  core libraries  |    Version:  4.10.x
Resolution:                  |   Keywords:  srfi-69, hash tables, locatives
-----------------------------+---------------------------------------------

Comment (by sjamaan):

 Actually, disregard that last comment: if an object is `eq?`, it must also
 be `equal?`, so the problem with mutation of the keys exists just as much
 for `equal?-hash` as for `eq?-hash`.
