If your original goal was to test for a ghc panic in newer ghc, my final
suggestion would be to get a minimal example that panics without all these
extra dependencies. If you happen to find that the bug exists in newer
ghc, you'd have to do that anyways to submit a useful bug report.

I done it, but got the same error. My project uses several my packages (libraries), they are called 'my-*'. I changed in their .cabal-files versions range of "base" too, but error is the same. Build-depends stanza of executable looks like:
build-depends: base >= 4.9 && < 4.11 , text , my-common-utils , my-atlassian-utils , my-jenkins-utils , my-git-utils , aeson , network-uri , network-info , text-show , hslogger , bytestring , transformers , aeson-pretty , time , email-validate , streaming , containers , sqlite-simple , directory , tuple , async , mime-mail , HaskellNet , HaskellNet-SSL , mustache , path , exceptions , mono-traversable , data-default-class , path-io , split , microlens , microlens-th , regex-pcre , pcre-utils , unordered-containers , formatting

Good, we're almost there!
I strongly suspect it is a base constraint. Go in your something.cabal file, build-depends section(s) and modify it from:
base >= 4.somenumber && < 4.10
to
base >= 4.somenumber && < 4.11
And try cabal new-build again. If that fails, please include the content of your `build-depends:` portion in your message -F _______________________________________________ Beginners mailing list Beginners@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/beginners
