The crash occurs since the build http://buildbot.python.org/all/builders/AMD64%20NetBSD%205.1.2%20%5BSB%5D%203.x/builds/891/.

The build was triggered because of the new changeset ae5c4a9118b8a3f490f77f2084d46163ca229aef, but I don't see a link between this changeset and ctypes. I may be another change in the toolchain, a system upgrade, or sometimes like that.

It looks like the crash is specific to Python 3.4.
