Bug#1149728: netgen: autopkgtest needs update for new version of (open)mpi(ch)

[Paul Gevers]

Source: netgen
Version: 6.2.2606+dfsg1-1
Severity: serious

Dear maintainer(s),

With a recent upload of mpich and openmpi the autopkgtest of netgen 
fails in testing when that autopkgtest is run with either the binary 
packages of mpich or openmpi from unstable. It passes when run with only 
packages from testing. In tabular form:

                        pass            fail
mpich                  from testing    5.0.2-1
netgen                 from testing    6.2.2606+dfsg1-1
all others             from testing    from testing

I copied some of the output at the bottom of this report. The 
autopkgtest actually doesn't fail because the test fails, but because 
there is a deprecation warning on stderr. If you don't care about output 
to stderr in the future, you can add the allow-stderr restriction to the 
tests.

Currently this regression is blocking the migration of mpich to testing 
[1]. Of course, mpich shouldn't just break your autopkgtest (or even 
worse, your package), but it seems to me that the change in mpich was 
intended and your package needs to update to the new situation.

If this is a real problem in your package (and not only in your 
autopkgtest), the right binary package(s) from mpich should really add a 
versioned Breaks on the unfixed version of (one of your) package(s). 
Note: the Breaks is nice even if the issue is only in the autopkgtest as 
it helps the migration software to figure out the right versions to 
combine in the tests.
