Segfault during compilation on Ubuntu 20

[coding-red-panda]

For one of our older projects, we use libv8 3.16.14.19 and this doesn't seem to compile on Ubuntu 20.
All requirements are installed from what I can tell:

Got the same problem here.
Has anyone found a solution for this?

So far we've just decided to stop using this gem and therubyracer and have NodeJS installed on the machines.
Get's the job done as well in our case and bypasses the problem, since there's also issues installing these gems on new Macbooks.

• Read this.
• Urgently move to mini_racer+libv8-node which support glib, musl, aarch64-linux, and arm64-darwin.
• Still, I pushed 3.16.14.19.1 binaries out of good will, might or might not unlock by sidestepping the build.

Closing.
