See SourceRepository and SourceStamp Actual Results: SourceRepository and SourceStamp is mozilla-central's / mozilla-aurora's one Expected Results: Should be comm-central's / comm-aurora's one

And this problem is only Windows build.

The purpose of this bug is to adjust the configure logic so that a .mozconfig set up for comm-central can be used in the mozilla-central logic without needing to adjust or override any commands. 8f57b0340428 Joshua Cranmer — Bug 1040009 - Run mozilla-central's configure from the objdir, not objdir/mozilla, r=Standard8 CLOSED TREE. This bug moves the objdir from the current location of MOZ_OBJDIR/mozilla to MOZ_OBJDIR, which fixes a series of longstanding bugs about mozconfigs not working due to the presence of two distinct objdirs. A temporary workaround to keep automation working is included. An important implication of this change is that mozconfigs are now required for comm-central: if they are not provided, Firefox, not Thunderbird, will be built.

I can verify that this was fixed by bug 1084997 I can no longer reproduce the problem on the following nightly build. https://hg.mozilla.org/mozilla-central/rev/a255a234946e https://hg.mozilla.org/comm-central/rev/e6d1e266c21a Mozilla/5.0 (Windows NT 6.1; WOW64; rv:36.0) Gecko/20100101 Thunderbird/36.0a1 ID:20141028030203
