Comment (by mouse07410):

 > Note though, its not just an issue with llvm trunk. Its clearly present
 going back to 7.0 as you see it there as well

 Yes, I concur.

 > 1. Its uncommon, and no one has seen it before to report it. Seems
 unlikely, given as you get it building gcc

 Well, I personally doubt many people would build gcc with llvm, because
 all these compilers are somewhat alternative to each other. For example, I
 prefer to stay with Xcode clang, but for some cases need gcc - which I
 prefer to build with the Xcode clang.

 > 2. Its already been seen and bug reports exist for it, but nothing has
 been done. Someone should check llvm's bug system

 Possible... @kencu, would you be able to check with their bug system, and
 if this bug isn't there already - post a bug report there? I think you're
 the closest to them among us (I could be wrong here).

 > 3. Its specific to the way MacPorts builds clang

 To verify this, somebody would have to build LLVM from scratch (not via
 Macports), build Clang from scratch (pairing it to the above LLVM), and
 try to build GCC from scratch... Somewhat tough call...

 My bet is on (1), possibly (2).
