Ok, that finally led to something. I have no idea, why this is happening, or how to fix it, but I have isolated QWebEngine as the troublemaker. relevant portion of CMakeLists.txt: add_executable(linktest linktest.cpp) target_link_libraries(linktest PRIVATE Qt5::Test Qt5::WebEngineWidgets) add_test(NAME rkward-linktest COMMAND linktest) ecm_mark_as_test(linktest) relevant code: https://invent.kde.org/education/rkward/-/blob/work/diagnose_testfailure/rkward/autotests/linktest.cpp result: https://invent.kde.org/education/rkward/-/jobs/359945 (2/2 Test #2: rkward-linktest ..................Exit code 0xc0000135) Note that "new QWebEngineView();" does not even have to be called. It's enough that the line of code is present, directly or indirectly. In contrast - for instance - creating a KTextEditor::Document/View does not cause any trouble. (In case you are wondering: That branch is a toy branch with only the Windows CI enabled, and intended to be deleted. Feel free to use it for further testing, should that help.) Regards Thomas
