 Replying to [comment:27 gk]:
 > So, not adding `libssp.dll.a` solves actually both issues I had (the
 dynamically linking and the crashes). I might be tempted to pick this up
 to get it still into 9.0 or 9.5a1 if the former is too risky. :) (thanks
 again, Martin)

 Here we are. `bug_29013_v5` (https://gitweb.torproject.org/user/gk/tor-
 browser-
 build.git/commit/?h=bug_29013_v5&id=562fe8f1df0de8912c9eaf7ff8c3b4d989d4aa01)
 in my `tor-browser-build` repo and `bug_29013_v2`
 (https://gitweb.torproject.org/user/gk/tor-
 browser.git/commit/?h=bug_29013_v2&id=cb5ccc9e3b50e9d37a4c7a34a0c81418df38adfe)
 in my `tor-browser` one.

 The first patch is using our own `mingw-w64` which we build anyway and is
 just copying the .a libs over. The `tor-browser` patch essentially backs
 out the special treatment of mingw-w64-clang.
