I was able to reduce it further to a standalone case:
% cat lib/Unicode/EastAsianWidth.pm
package Unicode::EastAsianWidth;
use strict;
use base 'Exporter';
our @EXPORT = qw(InFullwidth);
sub InFullwidth {
return <<END;
END
}
1;
__END__
% perl -Ilib -e 'A::xx(); package A { use Unicode::EastAsianWidth; sub xx { split /[^\s\p{InFullwidth}]/, "x" } }'
perl: util.c:1880: Perl_croak_no_modify: Assertion `0' failed.
Aborted (core dumped)
%
Note that if the module is C<use>d before the package declaration, the assertion is not hit.
