Comment (by alexcrichton):

 As an update here, I've been commenting (https://github.com/rust-
 lang/rust/pull/55444#issuecomment-434015059) on that PR, but unfortunately
 this patch I don't think we can land upstream because it doesn't really
 produce a workable target (panics don't run destructors).

 For Tor though how much of this actually matters? I was under the
 impression that Firefox compiles with `-C panic=abort` which would bypass
 the exception runtime anyway. Does tor also do that or intentionally not
 do that? (or accidentally forget to pass a flag that does that?) Or does
 `-C panic=abort` still have linking issues?
