Indeed, $LANG is the root cause (any of $LC_* is not set). Unset of $LANG or 
LANG=en_US.UTF-8 helps in my environment, setting it to e.g. "C" does not help.

At least a workaround :-)

Issue #41248 was created 10 years ago but it didn't happen for me until I 
upgraded to the current or previous Macos version.

Thanks!

For every command which is not found a error similar error like this is printed:

objc_initializeAfterForkError to debug.

Xcode has been installed today. Then MacPorts has been updated to the latest 
version, machine is rebooted, issue continues to exist.

This is indeed a very long standing issue:
https://trac.macports.org/ticket/41248
https://trac.macports.org/ticket/68638

It appears that this crash is actually caused by gettext, when localizing the 
error message in the child process forked by bash.
