Subject: Strange failure when running under perl -d
Download (untitled) / with headers

(Run under AS 5.8.6 on WinXP) I have an app that uses an Attribute::Handlers based module. While trying to debug the app/module, when running under "perl -d", I get the following error when A::H attempts to resolve a freshly declared variable: test_count set to 2 Test 1 Can't use an undefined value as a symbol reference at C:/Perl/lib/Attribute/ line 16. at C:/Perl/lib/Attribute/ line 16 Attribute::Handlers::findsym('main', 'SCALAR(0x1b6e5cc)') called at C:/Perl/lib/Attribute/ line 180 Attribute::Handlers::_apply_handler_AH_('ARRAY(0x1c3475c)', 'CHECK') called at C:/Perl/lib/Attribute/ line 146 Attribute::Handlers::__ANON__[C:/Perl/lib/Attribute/]('main', 'SCALAR(0x1b6e5cc)', 'Sociable') called at C:/Perl/lib/ line 6 attributes::import('attributes', 'main', 'SCALAR(0x1b6e5cc)', 'Sociable') called at t\02shared_attr.t line 52 Debugged program terminated. Use q to quit or R to restart, use O inhibit_exit to avoid stopping after program termination, h q, h R or h O to get additional info. DB<1> The statement that causes the failure is my $foo : Sociable = 'foo'; Note that this seems to work fine when not run under the debugger. I tried to step thru the failing method; it appears there might be a timing issue wrt when lexicals get installed in the symbol table under the debugger ? I've worked around the issue by declaring attributes directly (no A::H), so I don't think its anything inherent in my code. Needless to say, this issue makes using A::H a bit challenging...
