Thanks jan for tracking this one..

Can we get this one fixed one way or another ? 32-bits builds are red since webrtc 57: http://buildbot.rhaalovely.net/builders/mozilla-central-i386 .. i know this'd need a patch to external code but.. Or should i give up any hope on native 32-bits builds ?

Totaly fine with patching upstream for this

Pushed by rjesup@wgate.com: https://hg.mozilla.org/integration/mozilla-inbound/rev/1b0cc6279e2c cast so 32-bit clang will compile r=dminor

Builds went green since this push : http://buildbot.rhaalovely.net/builders/mozilla-central-i386/builds/951 thanks !
