Unfortunately, I cannot reproduce this. Backspace works as expected for
me for the following program:
$ echo "main = getLine >>= putStrLn" > Test.hs
$ ghc -o test Test.hs
using both v7.10.3 and v8.0.1.
Could you please try the following program in C:
================== %>< ============================
fgets(s, 32, stdin);
================== ><% ============================
Does backspace work in that case?
