Ticket #5803 (closed bug: duplicate)
Chash on terminate during getLine
My steps 1) run ghci 2) load module 3) run function 4) interrupt on getLine operation by Ctrl+C
After that I get *** Exception: <stdin>: hGetLine: end of file ghc.exe: panic! (the 'impossible' happened)
(GHC version 7.0.3 for i386-unknown-mingw32):
thread blocked indefinitely in an MVar operation
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
So I just report it here.
