commit 4edbd21ab9244671cb77cf9a4de5e1126079146e Author: David Keeler <dkee...@mozilla.com> Date: Fri Mar 9 14:16:57 2018 -0800
Bug 1444532 - Fix a leak in SHA256 in nsHttpConnectionInfo.cpp. r=mayhemer, a=jcristau The original code (from bug 1200802) declared an XPCOM object as a static bare pointer, which for future reference is probably never the right thing to do. It might have worked if it was cleared before shutdown but it never was.
