Comment (by GordonBGood):

 Replying to awson: and thomie:

 I don't think this should have been closed:  Using GCH 64-bit 8.0.1 and
 the same binutils as always as version 2.5.1 (which is the one that comes
 with GHC both 7.10.3 and the new one) and LLVM 3.7, I still get segment
 faults for the compiled executable on Windows 7 64-bit.

 I think that just because the simple little test program runs doesn't mean
 the problem isn't still there, as Fanael: showed that the problem occurs
 when a page barrier is crossed; The compilation for GHC has changed
 significantly and it may well be that a little insignificant program no
 longer crosses a page barrier.  My much larger application perhaps does
 and triggers the same problem.
