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.
