    Description

      1. Build the attached project.
        No sanitizers needed.
      2. Run the resulting program, passing the attached .svg file: 
        ./report 37306.svg

        The running program will occupy about 2GB of memory. When you set

        ulimit -Sv 1900000

        before starting the program, it will crash.

      oss-fuzz found this as issue 37306. They will publish the details on November 16th.
