+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.
