1478065 - Massive Xpcshell debug failure on 2018-07-24 caused by bug 1477254

Status: RESOLVED DUPLICATE of bug 1477904

(Thunderbird :: Preferences, defect)

Description

[Jorg K (CEST = GMT+2)]

As is known from bug 1449357, TB overrides some M-C preferences, like network.auth.subresource-img-cross-origin-http-auth-allow.

This has caused problems in the past, and now it has hit again. We have a complete loss of testing in debug mode since all test fail like so:

TEST-UNEXPECTED-FAIL | modules/libpref/test/unit_ipc/test_locked_prefs.js | xpcshell return code: 0

PID 3908 | Assertion failure: GetPref<StripAtomic<bool>>("network.auth.subresource-img-cross-origin-http-auth-allow", false) == StaticPrefs::network_auth_subresource_img_cross_origin_http_auth_allow() (Incorrect cached value for network.auth.subresource-img-cross-origin-http-auth-allow), at /builds/worker/workspace/build/src/obj-thunderbird/dist/include/mozilla/StaticPrefList.h:1012

Here's a stack:
