You need to be root, or otherwise privileged.

As root, I can reproduce it here:
# /opt/v5.28.1/bin/perl -wle '$) = "2 2"; print $!; print $)'

2 2
# /opt/v5.30.0/bin/perl -wle '$) = "2 2"; print $!; print $)'
Invalid argument
2 0
#

Of course that makes it difficult to spot bugs like this from the testsuite. :(
