Did you mean to say that by using a pure guix environment, we can
achieve a high degree of isolation?

I tried what you suggested.  The mrustc invocation still succeeded.

Just for fun, I also made a simple wrapper program that lets me run
another program using the LINUX32 personality (see attached).  I think I
programmed it correctly, but C is not (yet!) my forte, so if I made an
error, please let me know.  From within the same pure environment, I
used this wrapper program to invoke mrustc in the same way, and it
_still_ succeeded.  That surprised me, since I expected it to fail.

Can you think of any other way I can try to reproduce the issue?
