Test failing in Debug mode

Version: master and v6.3.0, since 1fe0708
Platform: x86_64 GNU/Linux
Subsystem: test

The test for addons/repl-domain-abort is failing, when configure was run in debug mode:

./configure --debug && make -j48 test

The assertion in the test test/addons/repl-domain-abort/test.js fails:

/usr/bin/python tools/test.py --mode=release -J \
        addons doctool known_issues message pseudo-tty parallel sequential

With some debug statements, turns out the binding module cannot be found:

Error: Cannot find module '/usr/local/google/home/franzih/node/test/addons/repl-domain-abort/build/Debug/binding'

Should build/Debug be created or should the correct path be build/Release/binding?
