    Description

      1. Build the attached project.
        No sanitizers needed.
      2. Run the resulting program passing in the attached input file, e.g.: 
        ./report 51266.html

        The program will allocate more than 25GB of memory and keep growing. If the file is broken, could QTextDocument notice that and exit earlier?

      Google's oss-fuzz found this as issue 51266.
