      1. Build the attached project.
        No sanitizers needed.
      2. Run the resulting program passing in one of the attached input files, e.g.: 
        ./report 29381.md

      It takes nearly two minutes until the program returns. If the file is broken, could QTextDocument notice that and exit earlier?

      Google's oss-fuzz found this as issue 29381.
