Comment 8 for bug 1432882

(sorry, I meant of course "trusty", not "lucid", in the above post)

I confirm that the libclang from the above PPA (1:3.4.2-debian13trusty1) does work correctly in trusty. In other words, when I compile the example programs attached to this bug report with the libclang from this PPA, the errors about ia32intrin.h are gone and parsing is fully functional. I don't know if this is due to 1) a more recent upstream libclang version (3.4.2 vs 3.4), 2) a more recent debian base, or 3) tweaks specific to this PPA.

If someone familiar with the debian/ubuntu build system could take a look at the source of this PPA:
https://github.com/hATrayflood/llvm-ppa

... and compare to what is done for the official ubuntu packages, that would be great. I have tried myself, but the thing is so complex and globally unknown to me that I am completely lost. From what I could gather, it seems that the maintainer of the PPA actually has made a few modifications to the original debian packages, as can be seen from this diff file:
https://github.com/hATrayflood/llvm-ppa/blob/master/trusty/llvm-toolchain-3.4/debian.diff

Also, can someone else actually reproduce this issue on their side?

NB: Using the PPA libclang, the builtin search directories are similar to the original ubuntu version. So that lead was a dead end. Here is the output of -print-search-dirs:
