Crash happens both on 32bit as on 64bit systems

appears that llvn-clang is the issue here, don't know why.

Standard system gcc-4.2 works, macports gcc 4.8 works.

Ok. #69092 was the bug report that llvm-gcc-4.2 was being selected. Previously it didn't seem to cause a problem but with the updated version of xz I guess it's time to revisit that now.
