1617604 - Fallible nsTArray::EmplaceBack cannot be called

Status: RESOLVED FIXED

(Core :: XPCOM, defect)

Description

[Simon Giesecke [:sg] [he/him]]

It is syntactically impossible to call the fallible overload of nsTArray::EmplaceBack, since it has an argument after a parameter pack, and the other overload also begins with a parameter pack.
