Created attachment 194550 [details] Test project to reproduce exception With the attached test project the exception can be reproduced: 1. Import the project as is ("Import existing project wizard") 2. Open file A16.5.c 3. Go to line 30, column 16 4. Press Ctrl+Space Then the exception is thrown.
(In reply to comment #1) Thanks, I can reproduce the issue with: void xxx( XXX *ptr) { func(ptr,
