Thanks for this hint. We finally decided to ship Tor Browser with
OpenSSL 1.0.1n. I know this is not ideal but burning another two days
seemed not worth the issue given that using Tor Browser should be
working as expected. Moreover, upon further investigation we believe
that you can even point your browser to a system tor or compile your own
tor and put it into the respective Tor Browser directory without risking
memory corruption.
