Error running mach:

    ['web-platform-tests', '--include=webrtc/RTCRtpReceiver-getSynchronizationSources.https.html']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.
You can invoke |./mach busted| to check if this issue is already on file. If it
isn't, please use |./mach busted file web-platform-tests| to report it. If |./mach busted| is
misbehaving, you can also inspect the dependencies of bug 1543241.

If filing a bug, please include the full output of mach, including this error

The details of the failure are as follows:

Some recent change apparently made the multiprocessing code reenter
python with the arguments -s -c "..." instead of -c "...", which
broke the assumption of the hack.

Not relevant to the actual bug, but fyi you can write mach web-platform-tests --include=webrtc/RTCRtpReceiver-getSynchronizationSources.https.html as mach wpt webrtc/RTCRtpReceiver-getSynchronizationSources.https.html which is quite a bit shorter ;)
