Re: Serious bug in GHC 9.4 on basic math on aarch64

[Carter Schonwald]

agreed! This is a nasty one! (the only similar bug i remember in the past
is the double/float confusion in 7.6/7.8, but that was a much much harder
to trigger bug)

Thank you for bringing this bug to our attention Ian, we have triaged
it as highest priority and will include a fix in the next release in
the 9.4 series.

Cheers,

Matt

Serious bug in GHC 9.4 on basic math on aarch64

[Ian-Woo Kim]

Hi,

We found a reproducible error with a simple math test (div/mod) on
aarch64. (on linux, on macos), so we want to call for attention on
this.
https://gitlab.haskell.org/ghc/ghc/-/issues/22282
This was originally caught by this issue:
https://github.com/haskell-foundation/foundation/issues/571

Thank you!
