Bug#721617: pyliblo: FTBFS on sparc: testSendOthers (unit.ServerTestCase) ... Bus error (core dumped)

[Sebastian Ramacher]

Source: pyliblo
Version: 0.9.1-3
Severity: serious
Justification: FTBFS but built successfully in the past

pyliblo FTBFS on sparc:
| PYTHONPATH=$(ls -d /home/sramacher/pyliblo-0.9.1/build/lib.*-2.7) \
|                 python2.7 -m unittest discover -s test/ -p '*.py' -v

| make[1]: *** [test-python2.7] Error 138

I was able to reproduce this issue on smetana.d.o. liblo rebuilt with
debugging symbols gives me the following back trace:

Core was generated by `python2.7 -m unittest discover -s test/ -p *.py -v'.
Program terminated with signal 10, Bus error.

Backtrace stopped: previous frame identical to this frame (corrupt stack?)
