    Description

      1. Have a build of Qt including qtsvg.
        No sanitizers needed.
      2. Build the attached project: 
        qt-cmake /tmp/report/ && cmake --build .
      3. Run the resulting binary passing the attached input file as parameter: 
        ./report /tmp/report/56011.svg

        This is completely occupying a full CPU for more than two minutes.

      Google's oss-fuzz found this as issue 56011. They will publish the details on May 16th. You can find a backtrace in their detailed report.
