I'm pretty sure I know what's causing this, because I just encountered
the same issue with GHCi on x86_64/Linux.  I've fixed it in the HEAD,
and I'll make sure the patch gets merged for 6.4.1.

Thanks for verifying that this does actually happen for real on another
platform - we've been having some difficulty tracking down exactly why
it's been working on OpenBSD which allegedly also disallows exec of
data.
