Regression in 2.15.1: stack passes unknown flag -no-keep-hi-files to ghc 8.0

[andreasabel]

Stack 2.15.1 passes -no-keep-hi-files to GHC 8.0, crashing it: https://github.com/debug-ito/staversion/actions/runs/8159145946/job/22302754180?pr=11#step:7:477

ghc: unrecognised flag: -no-keep-hi-files
did you mean one of:
  -keep-hc-files
unrecognised flag: -no-keep-o-files
did you mean one of:
  -keep-s-files

Usage: For basic information, try the `--help' option.

Error: [S-6374]
       While building simple Setup.hs (scroll up to its section to see the error) using:

-no-keep-hi-files -no-keep-o-files

The flag -no-keep-hi-files has apparently only been added in GHC 8.2, according to the milestone in https://gitlab.haskell.org/ghc/ghc/-/issues/4114 .
Unfortunately, the GHC docs have no "since" info for flags, and the release notes for 8.2 do not mention this flag either.

Oh, this seems to be

• Stack 2.15.1 does not support GHC < 8.2.1 #6498

I searched only the open issues...

Shouldn't closing this issue at least entail patch to Stack 2.15.1 so that it outright refuses to build with GHC 8.0 and lower?

Checking that it can handle the requested GHC is part of the "type checking" of a stack command so to say, and I would like a proper "type error" rather than a "crash at runtime". (After all we are strongly typed Haskellers...)

Given your experience, I'll see if I can release a Stack 2.15.3 that fixes this soon.

Closing as duplicate of #6498, which I have re-opened.
