Comment:

 changeset:5a31f231eebfb8140f9b519b166094d9d4fc2d79 and
 changeset:31a7bb463b6a3e99ede6de994c1f449c43a9118c dealt with similar
 issue on ELFv2 PPC64 but for passed arguments for a function.

 There is a way to detect a prototype skew by building ghc with
 CFLAGS/LDFLAGS=-flto.
 With this hack i've fixed a few SIGSEGVs on ia64 where pointers differ
 from function pointers (like
 changeset:d82f592522eb8e063276a8a8c87ab93e18353c6b)

 GHC still has a lot of mismatching prototypes though.
