[Debian-med-packaging] Bug#820060: python-biom-format: broken on big-endian architectures

[Steve Langasek]

Package: python-biom-format
Version: 2.1.4+dfsg-1
Severity: serious

As seen at http://buildd.debian.org/python-biom-format, this package fails
to build on all big-endian architectures in the archive (mips, powerpc,
s390x).  While this build failure has only appeared with the upload of
2.1.5+dfsg-1, this is not a regression in that version of the upstream
source; instead, the package was already broken, but what has changed now is
that a new version of dh-python correctly finds the tests and runs them at
build time where before dh_auto_test was silently passing.

I'm not sure if this points to breakage in python-biom-format, or in
something lower down the stack that it depends on.  I've confirmed that
python-numpy autopkgtests run ok on powerpc (except for openblas - and the
tests can't be run on s390x because openblas is not built for that
architecture), and h5py autopkgtests run ok on s390x.  python-scipy's
autopkgtests fail with SIGABRT on both powerpc and s390x, maybe related,
maybe not (test_random_complex_exact (test_basic.TestLstsq) ... *** Error in
`python3.5': free(): invalid pointer: 0x1172c2a8 ***).

And hdf5 itself doesn't have any autopkgtests, and any build-time tests
pass; and h5py in any case should catch any bugs with its own testsuite
before python-biom-format.

So it seems most likely that this is a bug in python-biom-format itself
rather than any of its dependencies, thus assigning here.
