I have installed Kdevelop 5.1.1. When I type anything in a .c file (single letter) Kdevelop crashes.
I have followed this doc https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces and rebuilt kdevelop, kdevplatform, qtgui, ktexteditor, qtwidgets, qtcore with CFLAGS="-O2 -pipe -march=native -g" (my whole system is built with only those flags, except -g).

The crash happens in a .c/.h files, editing/saving makefiles works flawlessly. It also happens when the following plugins are disabled: cppcheck, class browser, code browser. Editing the very same files works fine in Kate and Kwrite.

Thanks for help

You're lacking debug symbols which makes the backtrace unusable, add FEATURES=splitdebug. https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces

This should be reported to upstream, though.

I reported it (with debugging symbols) upstream as https://bugs.kde.org/show_bug.cgi?id=382901

Update: upstream has replied that it is a JavaScript allocator problem. I emerged dev-qt/qtscript-5.7.1 with jit flag disabled. Now Kdevelop works fine. I hope that will not slow Qt down too much.

Thanks for the follow-up both in the upstream bug and in here. Please note that I can not reproduce that bug with qtscript[jit] enabled.
