H-Termination with start terms of the given HASKELL could be proven:

(0) HASKELL
(1) BR [EQUIVALENT, 0 ms]
(2) HASKELL
(3) COR [EQUIVALENT, 0 ms]
(4) HASKELL
(5) Narrow [EQUIVALENT, 30 ms]
(6) YES

(0)
Obligation:
mainModule Main 
module Main where {
import qualified Prelude;

(3) COR (EQUIVALENT)
Cond Reductions:
The following Function with conditions
"getChar |terminatorreturn terminator|otherwiseaIOE IOError_EOF;
"
is transformed to
"getChar  = getChar2;
"
"getChar1 True = return terminator;
getChar1 False = getChar0 otherwise;
"
"getChar0 True = aIOE IOError_EOF;
"
"getChar2  = getChar1 terminator;
"
The following Function with conditions
"undefined |Falseundefined;
"
is transformed to
"undefined  = undefined1;
"
"undefined0 True = undefined;
"
"undefined1  = undefined0 False;
