Haskeline eats console events when native Windows IO is used.

Summary

Winio bugs out out when:

-GHCup is installed, (8.10.6/7, 9.0.2), HLS, no stack -Haskell Platform is then installed from this site:

https://downloads.haskell.org/~platform/ 8.6.5

Steps to reproduce

Windows 10

Test getChar and getLine

Expected behavior

What do you expect the reproducer described above to do?

getChar will no longer capture the input, immediately echo-ing it to off. getLine will lock up the GHCI (or GHC compiled) instance.

Environment

• GHC version used:

9.0.2 / 8.6.5

Optional:

• Operating System: Windows 10
• System Architecture: AMD64 (with Meltdown mitigation patch)
