panic! (the 'impossible' happened) - thread blocked indefinitely in an MVar operation
I was trying to get out of GHCi anyway, but I got it to crash by doing the following:
Type ^c (control+c) Type at least two other characters (e.g. 'ab') (The first character is not echoed back) Press <Enter> key
Result: <interactive>:1:1: Not in scope: `b' Prelude> ghc.exe: panic! (the 'impossible' happened)
(GHC version 7.0.3 for i386-unknown-mingw32):
thread blocked indefinitely in an MVar operation
