Yes, I noticed this issue under x86 (thanks to the message #65).

I wrote this crappy patch:
http://anonscm.debian.org/viewvc/pkg-llvm/clang/trunk/debian/patches/14-multiarchi386.diff?revision=64&view=markup
it fixes the problem on my system.

I didn't spend much time on writing a nice patch for the issue. I
already did too much uploads to manage the various changes due to the
multiarch stuff.
