Qt Creator crashes when loading project
-
I successfully managed to build my project with Qt 5.5 on my Mac in debug-mode exactly once. Then, when switching to release, Qt Creator 3.4.2 suddenly crashed. Now, Qt Creator will crash every time while loading the project file. I already deleted the QtProject folder in home/.config and deleted the project.pro.user file. I also cleanly uninstalled and reinstalled Qt and freshly checked out the code from my repository. I could again start the build process but Qt Creator crashed during the build when encountering an error (I changed the code a bit and accidentally introduced a bug).
It seems that the project file can be read successfully but Creator crashes when parsing the C++ files. Before crashing, Qt Creator outputs the following lines:
Could not find make configuration file default. Error while parsing file /projectpath/project.pro. Giving up. Warnings while parsing QML type information of /QtFolder/5.5/clang_64/qml: dump of /QtFolder/5.5/clang_64/qml: Reading only version 1.1 parts. dump of /QtFolder/5.5/clang_64/qml: Expected only Component and ModuleApi object definitionsTerminal only holds the following line before crashing:
Info: creating stash file /projectpath/shadowbuildpath/.qmake.stashAnd the crash report reads as follows:
