HashMap trees generated in property tests are too flat and too small #438
Description
unordered-containers/tests/Strictness.hs
Lines 24 to 29 in 4da2c20
This hash function produces only values in the range [0..19]. As a result, a typical generated tree will have a BitmapIndexed root node that contains some Leafs and some Collisions. No Full nodes at all, and no internal/non-root BitmapIndexed nodes!
It seems very likely that some code added since #317 hasn't been tested at all. :/
