Comment (by gk):

 A more general update: a) I might indeed have been right with comment:11
 as I can compile a i386 ASan hardened Firefox 29 fine. Thus, I am back
 bisecting.

 b) Then I tried to get GCC 4.9.0 to compile in order to be able to make
 use of UBSan and the other tools that made Clang superior but it failed on
 Lucid with:

 }}}
 Could be our Gitian setup though, that is the culprit here. Anyway, using
 Precise outside of gitian compiles GCC 4.9.0 fine.
