ModOrigin: hidden module redefined and crash in ghci when completing module name
Summary
ghci crashes when I try to use autocomplete after writing import
, in a place that looks correct (not in strings or comments).
This has just started happening late in the morning, I was using it some hours before without problems.
Steps to reproduce
- In ghci, write
import
on an empty line. - Write any sequence of bytes other than a newline. For this example, I wrote
Data.M
. - Press Tab, or any other key supposed to trigger autocompletion.
ghci output the text below and exit with code 0.
ghci> import Data.Mghc: panic! (the 'impossible' happened)
(GHC version 9.0.2:
ModOrigin: hidden module redefined
Please report this as a GHC bug: https://www.haskell.org/ghc/reportabug
Leaving GHCi.
Expected behavior
ghci should display a list of all completions available for the text previously input.
