Function getBytes on ArrayBase type can crash with the following message:

internal error: ARR_WORDS object (0x...) entered!
    (GHC version 9.0.1 for x86_64_unknown_linux)

A better workaround is now in place via a0ae7f5

A fix from GHC team is also coming; todo: remove the workaround conditionally on fixed GHC versions.
