(Reading from logs) During tests on arm qemu seg faults and then skips tests and success with packages.
On i386 it runs tests and fails with "Name or service not known" during test_docxmlrpc (SimpleXMLRPCServer.py+SocketServer.py) which looks something that builder might block for reason.

And actually it is not tests, but run_profile_task on

Code:

profile-opt:
        @echo "Building with support for profile generation:"
        $(MAKE) clean
        $(MAKE) build_all_generate_profile
        @echo "Running benchmark to generate profile data:"
        $(MAKE) profile-removal
        $(MAKE) run_profile_task
        @echo "Rebuilding with profile guided optimizations:"
        $(MAKE) clean
        $(MAKE) build_all_use_profile

And debian/rules is explicitly asking profiled build (so it can easily disabled).
