init-pants intermittent FATAL: exception not rethrown Aborted (core dumped)

Hi, first thank you for the helpful actions!

I am trying to use init-pants@main and sometimes it works successfully and other times I get the following output from pants --version:

Run pants --version

FATAL: exception not rethrown
/home/runner/work/_temp/ec994eaa-ce00-453c-936d-273c1589d131.sh: line 1:  1906 Aborted                 (core dumped) pants --version
Error: Process completed with exit code 134.

Considering it is intermittent, the vague nature of the error, the 134 error code, and that it still prints the version, my best guess would be that it is close to a system resource limit. I am not running anything else at the same time.

Is there any way to limit the memory usage? Why would this be exhausting the 7GB actions runner limit?

Let me know if you need additional information. Curious if anyone else is seeing this.

Perhaps setting process_total_child_memory_usage could help? But it still seems odd that it would be using so much memory just initializing.

Assuming this is what I think it is, the fix(es) were backported to 2.15.0 and greater, but not to 2.14.x: are you able to try upgrading to 2.15.0?
