Repro case (decompresses to two files of almost one million lines and 76 MB each)
The crash happens on one of two very large files that represent binary data as character array. Not sure whether it is relevant that both header files are included by a third file. The binary data is some fake data, but sufficient to reproduce the problem.

Created attachment 123440 [details] Full backtrace Qt Version: 5.11.3 Frameworks Version: 5.54.0 Operating System: Linux 4.19.0-6-amd64 x86_64 Distribution: Debian GNU/Linux 10 (buster) Clang version (debian package version): 1:7.0.1-8 - What I was doing when the application crashed: When I open a particular project, the background parser starts updating its database. For a long time it shows 99% and one particular filename (I don't think it takes that long for that rather small file, I guess it just not updating the window). Eventually, kdevelop crashes. I don't interact with kdevelop at that time at all. The crash can be reproduced every time. Full backtrace as attachment.
