That reads:

   PGPLOT::pgband($mode,0,12500,12500,my $x,my $y,my $ch);

Probably this wants giving a default for x and y: https://github.com/PDLPorters/perl5-PGPLOT/blob/04883c847b83d156392f50b8cd0da6cc6eab69d0/PGPLOT.xs#L96-L110

Instead, what was needed was to use the NO_INIT feature. Thanks for the report! Released as 2.28.
