 We plan to have debug builds with ASan soon again, so I am inclined to
 leave that open for now to remind us of the issue.

 Close because there is no more hardened browser? Or keep open and move to
 be about one of the other tor browser builds?

 Bumping `binutils` to 2.27 does not help either.

 Some notes before I forget them:

 1) This is not selfrando related but happens with a normal ASan build done
 in our Gitian environment as well
 2) Not stripping the binaries solves the problem
 3) Building the code locally and stripping it works fine
 4) Stripping the Gitian build results locally breaks, too

Comment (by mikeperry):

 GeKo reports that the ASAN_OPTIONS line did not fix the problem for him in
 6.0a5, which was before selfrando.

 I will ping the self-rando people to see what they did differently to
 allow the text in that wiki entry to work.

 In #19515 and other bugs, we seem not to be getting full stack traces for
 issues.

 It is common just to get: "==537696==AddressSanitizer: while reporting a
 bug found another one. Ignoring." or similar, rather than something that
 could be converted with the symbolizer as per
 
https://trac.torproject.org/projects/tor/wiki/doc/TorBrowser/Hacking#ConvertASansstacktracemessage.

 As per https://github.com/google/sanitizers/issues/391, it sounds like we
 may just need to add fast_unwind_on_fatal=1 to our ASAN_OPTIONS? Or maybe
 we need to update/switch to the latest stack unwinder:
 https://code.google.com/p/chromium/issues/detail?id=490275

 I think it is pretty important to get this working, as I've experienced a
 couple crashes I couldn't do anything about. The ability to get valid
 crash report data from the wild from our hardened builds is extremely
 valuable.
