I got those sorts of errors on a Mac. NAB duplex and certain other tests
would fail with segmentation faults. This could be avoided by specifying
"-m32" as a compiler flag. Dave suggested in an email to me that NAB
could be trying to link against a 32-bit library somewhere. Thus,
specifying "-m32" as a compiler flag _may help in your case. In the
longer term, I'd argue for a real fix (as opposed to a mere workaround),
but I'm not sure how to start implementing such a "real fix".
I also found the same thing you report in the Antechamber tests, where
ash, sustiva and guanine would fail. Not always the same tests. The
charges would be off by small amounts, and the exact combination of
problems would seem to depend on the compiler and the choice of
architecture (-m32, -m64 or left blank).
pbsa_trx and the other pbsa tests would fail if built using gcc. If icc
was used, they would pass.
I haven't tried building on a Linux machine for a while, so I can't
speak about the current state of play there.
Ross, I've prepared a comprehensive list of all the tests that were
failing in my builds on a Snow Leopard mac. I could forward the list to
you, if you like. I didn't know how appropriate it would be to send it
to the list at large. Is it something you would find helpful?
