Comment (by albertov):

 Interesting... I've managed to sidestep the bug by changing unboxed
 vectors to boxed vectors (from the `vector` package).
 [https://github.com/meteogrid/sigym4-geometry/compare/ghc-9971?expand=1#diff-0
 These] are the changes I've made. So it seems related somehow to the use
 of unboxed vectors. Hopefully this helps.
