Oh this is nasty. But I think you need to notify upstream about this. A wild guess is probably a gcc-4.6.* fault but I need to examine bt more carefully.

Hi, 
  I'm running qting and kde overlay with everything (comprised qtcreator) from git. So it's rather difficult to test dev-util/qt-creator-2.3.x, and the environment would be totally different from the current one.

In any case if you really need a test I can revert to a more stable env.

P.S. dev-util/qt-creator-9999 work fine
