Resolving dependencies...
Error: cabal: Could not resolve dependencies:
[__0] trying: cabal-freeze-bug-0.1.0.0 (user goal)
[__1] rejecting: cabal-freeze-bug:+some-flag (constraint from config file,
command line flag, or user target requires opposite flag selection)
[__1] rejecting: cabal-freeze-bug:-some-flag (constraint from project config

After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: cabal-freeze-bug:some-flag,

Expected behavior
I expect the flags specified in the local project config to override the flags in the freeze file.

Describe the bug
In my project, I have a project freeze file that has flag settings for local packages set to
-some-flag
. I expect to be able to override this flag in the local project config, following the precedence order given in the documentation: https://cabal.readthedocs.io/en/stable/cabal-project-description-file.html#project-description-cabal-project-file .But when trying to build, I get a resolution conflict instead.
