Comment 4 for bug 1950193

Correction for building the test program:

1. Install libqt5svg5-dev, qtbase5-dev and their dependencies.
2. Build the attached project with the system's version of Qt:
   /usr/lib/qt5/bin/qmake test-2021-38593.pro && make
3. Start the resulting binary and pass the path to the included input file as first parameter:
   ./test-2021-38593 ./input.svg
   The binary should return immediately and without error messages. If it doesn't, you might be affected.
