This is not something new, as I noticed it quite a few times.

Reporting it now to see if you are aware of it and if we can do
something about it.

We get gcc segfaults every once in a while in Travis:

Thanks David. We had seen compiler segfaults internally in the past. Don't remember the versions which worked/did not work. We had to downgrade/upgrade the versions.
Are there plans to move to Ubuntu 20.04 or later?
