Btw since Ubuntu 18.04 and 20.04 both seems patched as of today, if anyone
wants to play with this, it can be reproduced on e.g. gcc:9.3 docker image
(https://hub.docker.com/layers/gcc/library/gcc/9.3/images/sha256-dd7c100e12ddbf4178f5cd524a869fa54f453d35bf1b5f287ec6b70e3230c2e4?context=explore),
or by using the following docker image
(https://hub.docker.com/layers/disconnect3d/repro-cve-2020-10029/latest/images/sha256-0d7cf62eee140c9a0039945f8fe2ff3c53b7670b663cb67feef57878ab92ee06?context=explore)
and command where I compiled the example in the cve-2020-10029 directory:

docker run --rm -it --cap-drop=ALL --net=none disconnect3d/repro-cve-2020-10029
/cve-2020-10029/a.out
