c-index-test.crash.txt
SemaCodeComplete.cpp will crash libclang when calling
clang_reparseTranslationUnit on it. This is reproducable with c-index-test:
env CINDEXTEST_EDITING=1 ./bin/c-index-test -test-load-source-reparse 5 local \
-x c++ -std=gnu++11 \
-D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS \

There is no crash when preprocessing the file first (clang -E) and running that
through c-index-test.
Attached are two stack traces, one from c-index-test which I used to reproduce
the bug. The original stack trace is from Qt Creator, which is different (and
maybe helpful?)
