I can't reproduce those :(

fixed with latest llvm.

Problem here is that we have to make distribution patch mesa/gallium to link 
with the shared library of llvm, this is done in Fedora, not sure about other 
distro. I don't know if there is away to detect if the user use mesa/gallium 
and then disable opengtl in that case.

For me the reasonable thing to do for Krita 2.4 is:
* support only OpenGTL 0.9.16 (and llvm 3.0): right now we support too many 
version of those, and some of the older llvm have issues with recent hardware, 
and we get a lot of poorly tested combination
* put mutex everywhere because there are some serious threading issue (I 
probably now how to fix them, but that will be for a later version of OpenGTL)
* make sure distribution use llvm shared libraries with mesa (OpenGTL 0.9.16 
only work with them)
