--- Comment #8 from Georg Koppen <gk at torproject dot org> --- While I am still unable to compile/test Firefox 24 with clang trunk I managed to compile it with clang's r196090 which is the one r205695 merged. And there the problem occurs as well. Thus, we know at least that it is not a GCC specific issue. Not sure about the problem in comment 3 yet which is probably better tracked in a different bug. I'll open one as soon as my build machine is not occupied anymore with bisecting the things related to the crash mentioned in the description.
