in reply to exports -- which module exports are used?

I get a segmentation fault error when I run this on code containing Switch (big surprise, right?):
$ cat #!/usr/bin/env perl use warnings; use strict; use Switch; use Data::Dumper; my $val = 7; switch ($val) { case 1 { print "number 1" } case [5..10,42] { print "number in list" } else { print "previous case not true" } } print "\n"; $ $ exports Segmentation fault (core dumped) $ $ perl -v This is perl 5, version 22, subversion 0 (v5.22.0) built for x86_64-li +nux etc... $

Strangely, I don't see a core dump file. If I comment out the use Data::Dumper; line, or if I move that line above the use Switch; line, I don't see the segfault error. It looks like if the Switch line is last, we get no errors.

I realize Switch is strongly discouraged, and I will attempt to convince the original code author to get rid of it.
