773790 - widget/gonk/nsWindow.cpp declares a global XPCOM object

Status: RESOLVED WONTFIX

(Core Graveyard :: Widget: Gonk, defect)

Description

[Dave Hylands [:dhylands]]

I observed the warning on my b2g otoro phone:
WARNING: XPCOM objects created/destroyed from static ctor/dtor: file /home/work/B2G-otoro/gecko/xpcom/base/nsTraceRefcntImpl.cpp, line 141

I ran it under gdb and got the following backtrace:

nsWindow.cpp:46 corresponds to the line:
static nsTArray<nsWindow *> sTopWindows;
