(Sorry for cross posting, but the topic is related to both side)
In Bash-5.2 there is a change:
"ff. Some fixes to how subshells modify $SHLVL."
This causes 134 test failures in autoconf. They look like:

While I think this is some innocent difference (it's unlikely a
package's building system can depend on $SHLVL), and we can simply "fix"
(or "paper over") it with

But I'd like to request some details about the SHLVL change from bash to
understand the test failures better and maybe fix them in a better way.
