My FreeBSD 10-CURRENT/amd64 boxes fail to build Thunderbird 13 compiling with CLANG. The error is very much the same as when I try compiling Firefox 13 on the same box with CLANG. I tried to track down the problem, but I failed. Bot systems are used to have very similar setups and ports, both boxes have FreeBSD 10.0-CURRENT/amd64 (FreeBSD 10.0-CURRENT #0 r236694: Wed Jun 6 23:06:12 CEST 2012), both OSes have been compiled with CLANG. The box in question is a very new Sandy-Bridge-E system with 32GB RAM, while the box compiling well is a older Core2Duo (I mention this since I read about differences in how LLVM/CLANG 3.1 may behave on different CPUs, even with -O2 enabled). I'm confused about this, since Firefox 13 and even 12 fail at the same point with a very similar error message in this "xpcom" module. On the box in question, I already did a "portmaster -f thunderbird" to force every prerequisite been built, but with no success. By the way: I use "WITH_NEW_XORG" in /etc/make.conf. I don't know whether this is an issue or necessary hint ... Any help appreciated.
