file, causes the error durig the parse

Kdevelop falls with sigsegv parsing my project. Last file he tried to parse was the attached one.

This is my first bug report - please< tell me if I need to provide smth else
Comment 1 Kevin Funk 2018-04-26 05:56:31 UTC 
Heya Yuri,

unfortunately it's not possible to reproduce the crash using your file (it is not standalone, needs other includes, thus cannot be parsed properly here).

It would be best if you could supply a backtrace of your crash, please check out the following link to see how to create a crash report on Linux:

Please tell if it's not useful, i'll provide something else
