Comment (by gk):

 Some updates. The good news is I get it built (thanks to ted for the idea
 of using `--disable-startupcache`). Mozilla is not running LSan currently
 due to various issues comment:52 being one of them
 (https://bugzilla.mozilla.org/show_bug.cgi?id=1214464) and LSan breakage
 of the packaging step a second one
 (https://bugzilla.mozilla.org/show_bug.cgi?id=1215443).

 The bad news is it crashes during start-up with
 {{{
 /home/ubuntu/build/tor-browser/tools/profiler/UnwinderThread2.cpp:693:66:
 runtime error: null pointer passed as argument 2, which is declared to
 never be null
 /usr/include/bits/string3.h:52:71: runtime error: null pointer passed as
 argument 2, which is declared to never be null

 ASAN:SIGSEGV

 which we already saw in comment:54.
