Errors when trying to generate a test coverage report about containers HOT 10 OPEN

@clyring, I've filed the first issue upstream as #24608.

from containers.

Of course, deleting those uses will prevent us from checking coverage of the relevant paths. Have you filed a GHC ticket? That first thing is an obvious compiler bug!

СС @BinderDavid for hpc.

This might have been fixed by haskell/cabal#9464 . What is the version of cabal that has been used?

This looks very different; it's complaining about an incomplete pattern match in the compiler when lowering STG to cmm.

Issue 1 is certainly a ghc bug. Do you want to file the upstream report? I think I know what's happening there; if I'm right I should have time to prepare and test a patch this weekend.

I can probably do it sometime tonight, but I won't feel bad if someone beats me to the punch.

@meooow25, issue 1 seems to be confined to the definition of hetPtrEq, which we don't actually use anywhere. So just deleting it should be a safe workaround.

@BinderDavid , ah, you were talking about the second issue. My bad.

@BinderDavid I'm using the latest Cabal 3.10.3.0
