commit e4848686fd6078cd9cbdf3c8a9fe979f0f9a7283 Author: Georg Koppen <gk(a)torproject.org> Date: Fri May 12 13:05:35 2017 +0000 fixup! TB4: Tor Browser's Firefox preference overrides. Hide the TLS error reporting checkbox for now as Mozilla seems to be the wrong party to get Tor Browser reports. One day we might want to repurpose this checkbox to point to our own infrastructure to help finding bad relays (see bug 19119).

[tor/master] Untangle cleanup logic in test_hs_intropoint.c

commit 61a367cadd235dacf3cdc5543ba261dfee66f5d4 Author: Taylor Yu <catalyst(a)torproject.org> Date: Thu May 11 12:55:18 2017 -0400 Untangle cleanup logic in test_hs_intropoint.c Cleanup logic in test_intro_point_registration() invoked tt_assert() in a way that could cause it to jump backward into the cleanup code if the assertion failed, causing Coverity to see a double free (CID 1397192).
