Bug#699866: clang crashes while translating a trivial C++ program

[Galin Hristov]

This is the output of:
clang test.cpp
executed on qemu emulated ppc with debian 3.2.0-4-powerpc #1 Debian 3.2.35-2 ppc GNU/Linux

The first that catch the eye (at list mine) is "-triple powerpc-unknown-linux-gnu " and "1.


   parser at unknown location". Ok, they are two things that got my eye. Anyway, hope it helps.
