There isn't any magic environment we can share here I'm afraid. We
don't know why it happens on some autobuilder workers and not on
others, this is something we need to investigate and fix. This is one
of the challenges of these "intermittent" issues.

The errors seem to relate to zlib so it may be worth looking at whether
host headers influence the rust build and those may be causing some
kind of determinism issue. You may have to build the binaries one a
system with the headers, then run them on a system without for example.
