test.cpp
I ran the file test.cpp from the attached tarball through c-index-test, and
libclang consistently crashes:
erik@Road-Warrior:qtcreator_test$ env CINDEXTEST_EDITING=1 c-index-test

./test.cpp:1:10: error: 'skeletons/xcoder_exception.h' file not found with
<angled> include; use "quotes" instead

found
