Yes, I see that.  GHC keeps these values as Integers internally, so it's 
possible that some misconfiguration has caused it to produce a values 
that's out of range, although I agree that the fact that it is bigger 
than even 2^64 is quite suspicious.

I suggest dumping out some intermediate code, e.g. -dppr-cmm 
-dppr-opt-cmm.  If that fails to narrow it down, then you may need to 
add some debug traces the native code generator to find out where these 
values are coming from.
