Comment (by RyanGlScott):

 The issue isn't GHC 7.6.3 vs. 8.0.2. Rather, it's a 32-bit vs. 64-bit
 Windows GHC difference. I tested the program on GHC 7.10.2, 7.10.3, and
 8.0.2 using both the 32-bit and 64-bit versions, and the 32-bit versions
 all succeeded whereas the 64-bit versions all failed the second test.
