The Native_Word entry in the AFP contains a number of quickcheck[narrowing] calls that are
set up such that they are tested only if ISABELLE_GHC is set. Therefore, there cannot be
an error message about quickcheck narrowing if ISABELLE_GHC is not set.

Just had a very strange experience with ISABELLE_GHC.
You will have noticed that the AFP test failed the last few days with GHC
compilation errors.
The AFP test settings included the line
ISABELLE_GHC=/opt/local/bin/ghc
Apparently, this caused sessions like Native_Word to fail, even though that is
where ghc is installed on this machine (macbroy2). ghc also happens to be in
the PATH on macbroy2 (pointing to the same /opt/local/bin/ghc), so in an act of
desperation I tried locally removing the above line on the isatest account.
Voila, Native_Word builds fine.
This was on isabelle 2bfbeb0e69cd and afp 4ea6558c319c.
However: on my laptop, with ISABELLE_GHC=/usr/bin/ghc, everything works fine.
Either it’s something about the path or something about the macbroyX machines.
Any ideas what could be going on?
Cheers,
Gerwin
