I disagree, there is no reason why PHP can't reset the CWD to the correct directory when a shutdown handler is run. That is what I would expect to happen.

Didn't work. :)

While it shouldn't be hard to restore the CWD during the shutdown
handler, I wonder whether we should do it.  After that long time,
most code likely has adapted to do this manually (or doesn't use
relative paths in the first place), and some code may even use the
CWD reset on purpose (BC break).

Anyhow, this change is unlikely to happen, unless somebody submits
a PR.
