bug#31215: coreutils env fails in a bash shebang |

I think I've found a bug in *coreutils*, *env*.
Linux debian 4.9.0-4-amd64 #1 SMP Debian 4.9.65-3+deb9u1 (2017-12-23)
x86_64 GNU/Linux
All my Perl scripts contain either of these shebangs:
#!/usr/bin/env perl -w
or
#!/usr/bin/env perl -wd
When I attempt to run a Perl script with either of these shebangs in debian
I get:
/usr/bin/env: ‘perl -w’: No such file or directory
It is not perl that can't be found; it is either *env*'s or *bash*'s
handling of the argument. If I remove the *-w* and/or the *-wd* arguments
the scripts execute, but of course, without the benefit of those switches.
The man page for *env* asserts that any command may take an argument. I
have tried every way I can think of to quote the *-w* and the *-wd* but
*env* is treating these perl command line arguments as filenames, and since
they aren't files, renders that error message. I'm running the latest
*coreutils* as in this apt-get fragment:
Reading package lists... Done
Building dependency tree
Reading state information... Done
coreutils is already the newest version (8.26-3).
Both of these shebangs work correctly in macOS 10.13.3 with the native perl
from Apple and perlbrew perl. That is where I do most of my perl work but
now I need to move those scripts to debian, without changing the shebangs.
Is this a bug in *env*, something in bash or pilot error?

T.W. Schmidt
