Public bug reported:
Description:
Objects of the data section may be accessed through tagged pointers. Thus,
those objects require a minimal alignment of 8 byte on a 64-bit architecture.
Otherwise, this may lead to undefined behavior.
Solution:

https://gitlab.haskell.org/ghc/ghc/-/commit/dfe1c3540e4b519b62b862b5966dfec5cae9ece1
This patch resolves the alignment issue for all targets utilizing the
LLVM backend. The fix was backported by upstream for ghc release 9.6 and
9.8 but not for 9.4.x which has landed in Noble.
