[...] Notice however that if I compile with the "-prof -auto-all -O" flags then I got the following error message when I try to examine the interface file (with --show-iface) :

This has been fixed in GHC 6.x, as a workaround you can use the undocumented option "-buildtag p" *before* --show-iface, e.g. ghc -buildtag p --show-iface Foo.p_hi Cheers, S.
