Bug #45718 for Parse-BBCode: Cannot use the same tags hash more than once

In the following code my %tags=(Parse::BBCode::XHTML->defaults); my $bb1=Parse::BBCode::XHTML->new({tags=>\%tags}); my $bb2=Parse::BBCode::XHTML->new({tags=>\%tags}); print "FAIL\n" if $bb1->render("\n") ne $bb2->render("\n"); the two BBCode objects do not produce the same output despite being created with the same parameters. The first one gives the correct output which is "<br />\n", but the second one gives "\n". The reason seems to be that the Parse::BBCode::XHTML->new method modifies the %tags hash in a way that the new hash is not equivalent with the original one. This is why the following works just fine: my %tags=(Parse::BBCode::XHTML->defaults); my $bb1=Parse::BBCode::XHTML->new({tags=>{%tags}}); my $bb2=Parse::BBCode::XHTML->new({tags=>{%tags}}); print "FAIL\n" if $bb1->render("\n") ne $bb2->render("\n"); I think the constructor should make a private copy of this hash so that it can modify it safely.
