Bug #47547 for Devel-Declare: D::D and source filters

Fri Jul 03 11:57:24 2009 zefram [...] fysh.org - Ticket created

Subject:	D::D and source filters
Date:	Fri, 3 Jul 2009 16:56:54 +0100
To:	bug-Devel-Declare [...] rt.cpan.org
From:	Zefram <zefram [...] fysh.org>

The attached test script demonstrates a bad interaction of Devel::Declare with source filters. The code sets up a no-op Devel::Declare arrangement, which is never used. It also uses a very simple source filter, to inject a small piece of test code by a roundabout route; the filter deletes itself as soon as it is invoked. When parsing reaches the end of the file, the compilation dies with the error message "filter_del can only delete in reverse order (currently)". If the filter is applied *before* the Devel::Declare setup, everything works as expected. It only fails when the filter is applied afterwards. Don't know whether this is a bug in Devel::Declare, Filter::Util::Call, or the perl core. -zefram

perl5i just banged into this bug. If a thing which uses Devel::Declare is run before a thing which uses Filter::Simple then toke.c throws up its hands in disgust. # For example use Method::Signatures; use Data::Dumper::Simple; A simple Filter::Simple module will set it off. package Foo; use Filter::Simple sub { 1 }; The error is inside toke.c in Perl_filter_del.
