      1. Have a build of Qt including qtimageformats.
        I used a release build of Qt 6.4.0 without sanitizers.
      2. Use this to build the attached project, e.g.: 
        qt-cmake /tmp/report/ && cmake --build .
      3. Run the resulting binary passing the attached input file as parameter, e.g.: 
        ./report /tmp/report/49080.tiff

        You will see many, many warnings and the memory consumption will grow until the entire system stutters.

      Google's oss-fuzz found this as issue 49080. They will publish the details on October 11th.
