Comment:

 Replying to [comment:3 gk]:
 > Okay, I bisected the problem (`PIE` enforcement breaks the compiler) and
 pushed a fix for review to bug_20301
 (https://gitweb.torproject.org/user/gk/tor-browser-
 bundle.git/commit/?h=bug_20301&id=dfa3403825fc315168df3295f6062f5979b0a8a0)
 in my public repo.

 I applied the same fix, using the same comment, to tor-browser-build in
 branch `bug_20301`:
 https://gitweb.torproject.org/user/boklm/tor-browser-
 build.git/commit/?h=bug_20301&id=4e57f8a0780fd9ed9633dc7d2391bf908b74e337
