i'm using 2 functions simultaneously, one that takes input with getChar and other that draws some characters con the terminal, however, i'm using ansi-terminal to move the cursor on the screen the problem is that when i compile throws the next error

user error (pattern match failure in do expression at libraries\Win32\System\Win32\Types.hsc

this only happens when i set "+RTS --io-manager=native" flag, but that is necesary 'cause getChar doesn's work properly without it

This has been fixed in version 2.12.0.1 of Win32. See this issue.

If you're using cabal I think you can make a cabal.project file with these contents:

packages: .

constraints: Win32 >= 2.12.0.1

Or if you use stack I believe you can add Win32-2.12.0.1 to your extra-deps in your stack.yaml.
