Comment 2 Vladimir Kvashin 2016-10-11 08:52:38 UTC

Steps to reproduce: copy an LLVM34 project from perf-linux, open it, answer "no" on the proposal to consider .inc files as C++.

This should be already fixed in 28ab2964f78c at enum/release82
Although more investigation is needed to understand why this did not happen before.

Comment 3 Vladimir Kvashin 2016-10-11 11:06:20 UTC

In most places there were null checks for CompletionSupport.get() return; but in some places they were absent. I added null checks for all calls they were absent:
f650660afb55 (enum/release82).
