Comment 3

[Jan Alexander Steffens [:heftig]]

Firefox Nightly builds on Arch Linux have started failing with the same error. The regressor is probably bug 1986593. TemplateLib.h (included through nsCycleCollectionTraversalCallback.h → nscore.h → mozalloc.h) used to include <type_traits> for the use in nsCycleCollectionNoteChild.h but that is now missing.
