Comment (by cypherpunks):

 [https://dxr.mozilla.org/mozilla-
 esr45/source/security/nss/lib/pk11wrap/pk11cxt.c#48 This] is about wrong
 slot:
 {{{
     if ((cx->ownSession) && (cx->slot->isThreadSafe)) {
 }}}
 Probably points to freed memory, else NULL would trigger for all another
 platforms too. If correct then should be reproducible for hardened Tor
 Browser too.
