This broke some time between 1.29 (perl 5.18) and 1.3301 (perl 5.20):
|
|
|
|
$ perl5.20.1 -e 'package Foo { use constant ISA => 42; Bar::f() } package Bar { use Carp; sub f { carp "tun syn" } }'
|
|
Not a GLOB reference at /usr/local/lib/perl5/5.20.1/Carp.pm line 560.
|
|
|
|
and still persisted in bleadperl (Carp 1.43) until this commit.
|
|
|
|
The code that goes poking through the symbol table needs to take into
|
|
account that not all stash elements are globs.
|
|

|
Petr Písař: Ported to 5.24.3.
