A month ago, nsStyleDisplay::IsInlineOutside changed to be called "IsInlineOutsideStyle": https://hg.mozilla.org/mozilla-central/rev/d7749fadb594#l13.41 ...and a new IsInlineOutside method was created that requires an argument: https://hg.mozilla.org/mozilla-central/rev/d7749fadb594#l13.67 This broke some ifdeffed-off flexbox code (which is only noticeable when you #define MOZ_FLEXBOX). I've had a fix for this in my tree for a while, but hadn't posted it on a bug yet. The error is: { ../../../mozilla/layout/base/nsCSSFrameConstructor.cpp: In member function ‘void nsCSSFrameConstructor::CreateNeededAnonFlexItems(nsFrameConstructorState&, nsCSSFrameConstructor::FrameConstructionItemList&, nsIFrame*)’: ../../../mozilla/layout/base/nsCSSFrameConstructor.cpp:9562:66: error: no matching function for call to ‘nsStyleDisplay::IsInlineOutside() const’ ../../../mozilla/layout/base/nsCSSFrameConstructor.cpp:9562:66: note: candidate is: In file included from ../../../mozilla/layout/base/../generic/nsIFrame.h:3204:0, from ../../../mozilla/layout/base/nsGenConList.h:11, from ../../../mozilla/layout/base/nsQuoteList.h:11, from ../../../mozilla/layout/base/nsCSSFrameConstructor.h:18, from ../../../mozilla/layout/base/nsCSSFrameConstructor.cpp:14: ../../../mozilla/layout/base/../style/nsStyleStructInlines.h:92:1: note: bool nsStyleDisplay::IsInlineOutside(const nsIFrame*) const ../../../mozilla/layout/base/../style/nsStyleStructInlines.h:92:1: note: candidate expects 1 argument, 0 provided } For reference, the cset that broke this was: https://hg.mozilla.org/mozilla-central/rev/d7749fadb594#l13.41 Fix is just s/IsInlineOutside/IsInlineOutsideStyle/ -- attaching it in a minute.
