QtWebEngine crashes on Linux with 64kb page size

QtWebEngine crashes on Linux with 64kb page size with an error message "Render process exited with code 133".

Tested on Qt versions 6.2.2, 6.2.4, 6.3.0, 6.3.1

The issue can be reproduced even on a Qt example "simplewebbrowser".

Dockerfiles where the problem can be reproduced are attached (they will generate in a shared directory rendering_error.jpeg with a screenshot of an error).
For clang build:
 

docker build -f Dockerfile.clang -t qt_631_vnc:1.0 .
docker run -v /dev/shm:/dev/shm -v /tmp/64kb_error_output_clang:/output -it qt_631_vnc:1.0

For GCC 9 build:

docker build -f Dockerfile.gcc -t qt_631_gcc_vnc:1.0 .
docker run -v /dev/shm:/dev/shm -v /tmp/64kb_error_output_gcc:/output -it qt_631_gcc_vnc:1.0
