[m-users.] mmc --make giving strange warnings/errors

[Kilian Evang]

Hi all,

I've recently started around playing with Mercury and am concerned about
strange warnings/errors I get for some programs when trying to mmc
--make them. I've attached a minimal example (test.m) and the error
output I get (test.err).

In this case, it seems to be the type declaration in the implementation
part that triggers the error. If I remove it or move it to the interface
part, the program compiles quietly.

As far as I can tell, the generation of working executables is not
affected, it's just perplexing and worrying.

My OS/Mercury version:

ke at apis:~/mercury$ uname -a
Linux apis 3.11.0-15-generic #23-Ubuntu SMP Mon Dec 9 18:17:04 UTC 2013
x86_64 x86_64 x86_64 GNU/Linux
ke at apis:~/mercury$ mmc --version
Mercury Compiler, version 13.05.2, configured for x86_64-unknown-linux-gnu
Copyright (C) 1993-2013 The University of Melbourne
ke at apis:~/mercury$

Any ideas what is wrong?

Cheers,
Kilian
