-Subject: [PATCH] Data/Map/Static/Builder.hs: avoid shiftL with negative offset
-
-On ghc-8.8 building `encoding` fails as:
-
-```
-Preprocessing library for encoding-0.8.5..
-arithmetic overflow
-```
-
-This happens because `findSplitSize` can't handle
-small values, like `findSplitSize 1` and calls `shiftL`
-with negative value, which is forbdden:
- https://hackage.haskell.org/package/base-4.14.0.0/docs/Data-Bits.html#v:shiftL
-
-Work it around by always passing non-negative offset.
