ghc panic, "impossible" happened while running tests, failed to load shared object
Here's the message I got from within GHCI. (The first line is the command, tests
, that I had just run.)
> tests
ghc: panic! (the 'impossible' happened)
(GHC version 8.6.3 for x86_64-unknown-linux):
Loading temp shared object failed: /tmp/user/1000/ghc24072_0/libghc_36.so: undefined symbol: RsltziRValid_validRslt_closure
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
Here's the commit of the branch of the code I was working on when this happened.
I keep the test suite in the main body of code, so that I can run it from within GHCI. That's what I was doing when it happened.
