- Have a build of Qt including qtsvg.
No sanitizers needed. - Build the attached project.
qt-cmake -S /tmp/report/ && cmake --build .
- Run the resulting program and pass the input file.
time ./report /tmp/report/41331.svg
You will see error messages and it will take too long until the program returns:
qt.svg: link #a is undefined! qt.svg: link #-polytonc is undefined! qt.svg: link # is undefined! qt.svg: link # is undefined! qt.svg: link #directionc is undefined! real 0m18,880s user 0m16,749s sys 0m0,072s
While it runs, the program fully occupies a CPU core.
When built on Qt 6.1.3, the program returns immediately:
qt.svg: link #a is undefined! qt.svg: link #-polytonc is undefined! qt.svg: link # is undefined! qt.svg: link # is undefined! qt.svg: link #directionc is undefined! real 0m1,139s user 0m0,061s sys 0m0,042s
Google's oss-fuzz found this as issue 41331. They will publish the report on February 21st.
