    Description

      Steps to reproduce:

      • Check out the Qt repos from git (5.15 branch).
      • Perform a build from command line
      • Open PROJECT/qtdeclarative/src/src.pro in Qt Creator and import the build configuration from the build folder

      Qt Creator will run for a while and finally perform the step "Scanning for tests..." which takes a while. At some point it crashes.

      Here is the backtrace:

      Thread 22 "Thread (pooled)" received signal SIGSEGV, Segmentation fault.

      I only tried Qt 5.15 from git, but I am pretty sure that this worked some time in the past, e.g. in the Qt 5.12 branch. The problem persists in Qt Creator 4.12.0-rc1.

      Everything works when opening sub projects of src.pro, for instance qml.pro. Is this reproducible?
