Created attachment 140920 [details] change causing kdevelop crash SUMMARY Short story long: saw that ECM 5.85.0 comes with optional stricter compiler settings so decided to turn them on and work through them (project is https://sourceforge.net/p/kuroo). STEPS TO REPRODUCE 1. Fetch revision #1657 of https://svn.code.sf.net/p/kuroo/code/kuroo4/trunk 2. Apply attached patch 3. Trigger clang reparse of the project OBSERVED RESULT KDevelop crashes, console output: ``` $ kdevelop QSocketNotifier: Can only be used with threads started with QThread kdevplatform.serialization: version mismatch or no version hint; expected version: 84279809 kdevplatform.serialization: "The data-repository at /home/andrew/.cache/kdevduchain/kdevelop-{83555a53-d447-4862-b0f6-024f33d6573b} has to be cleared."
