I put:
compiler: ghc-8.2.1
in the stack.yaml of my project which picks up the right version.
This didnt work prior to my current stack version 1.6.1

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

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.
