[Qt-creator] C++ indexing stucked

[Christian Gagneraud]

Hi there,

I'm having problems with code model and indexer, once a sqlite DB was
corrupted (I don't know how), but even after removing this DB I still
have issues with this sqlite DB.

---------------------------------

This is a relatively small project and it builds fine for Android and
Linux desktop, both using clang.
As well, QtC takes ages to exit.

OS: Ubuntu-18.04
QtC:  4.11.2
Experimental plugins:
 - ClangRefactoring
Code model:
- ambiguous headers: no
- ignore pch: yes
- 5MB limit: yes
- diags: questionable constructs

Disabling ClangRefactoring plugin seems to fix the problem. Is this a
known issue?

Thanks,
Chris
