[bind10-dev] python Segmentation fault in notify_out_test.py

[Jeremy C. Reed]

Tests on NetBSD have been failing like:

Running test: notify_out_test.py
..............[1]   Segmentation fault (core dumped) PYTHONPATH=/home...
*** Error code 139

http://git.bind10.isc.org/~tester/builder/BIND10/20121030163907-NetBSD6-i386-GCC/logs/unittests.out

This happens with python31 and python32. Here is a backtrace:

Core was generated by `python3.2'.
