Hi! I'm building a project with pants and running into the following error any idea why it might be seg faulting?

Hi! More detail is usually helpful: platform (looks like macos?). architecture, pants version, pants command. That said, this is likely a segfault inside pip (which is executed by pex). So the best thing is to try and reproduce outside of Pants. E.g., you can run with 
--keep-sandboxes=on_failure
, find the relevant sandbox (which will be for a pex invocation) and see if this error reproduces when you 
./__run.sh
inside that sandbox. If so, you now have a repro involving just pex. Then you can inspect that run’s logs to get the underlying pip command and see if you can isolate to just pip. And the pip logs will be instructive to see where it segfaulted.

macos m1, pants version is 2.19.1
have a few commands giving me this issue here's the most recent one i ran that just runs unit tests in the project 
pants test projects/common/spark_join/tests/::
i have managed to get the 
__run.sh_
and that does give me the same error, i dont know if the log is giving me more info let me run it again now
this is the output when i run the run.sh commands 
exited with -11 and STDERR: None
Okay managed to get the following log from pex

if anyone happens to run into something similar this ended up being the issue: https://github.com/pyenv/pyenv/issues/1048

So a homebrew upgrade issue?
Good to know!
