Sample project

In the attachment there is a small project which illustrates false positive/strange behavior of C/C++ Code Analysis.

Steps to reproduce:
1. Import project to Eclipse
2. Do a C/C++ Code Analysis - no errors reported
3. Rename zzz.cpp to yyy.cpp
4. Do a C/C++ Code Analysis - error reported in rrr.h "Type 'tUUUtype' could not be resolved"

PS: rrr.h doesn't include uuu.h as it should, but that should not mind. It's included in zzz.cpp before rrr.h.

Note that rebuilding the project's index after the rename solves the problem.
Comment 2 Nathan Ridge CLA 2018-07-12 03:33:41 EDT 
The root cause is likely the same as bug 441752: the incremental index update performed after the rename misses some things that should be updated.
