Subject: Stringification crashes on a closed IO::Scalar handle
Download (untitled) / with headers
text/plain 1023b
Hi! I would like to be able to stringify any IO::Scalar handle (regardless if it was previously closed or not). However when an IO::Scalar handle is closed, stringification will *always* crash a program. Here is a minimal code that demonstrates the bug and the results of its execution: $ cat ./ #!/usr/bin/perl use IO::Scalar; $var = new IO::Scalar; $var->close; print "$var"; $ ./ Can't use an undefined value as a SCALAR reference at /usr/local/share/perl5/IO/ line 157. $ echo $? 255 I confirmed it to crash in the latest version of IO::Scalar (2.111) package. It could be fixed easily for example by replacing an overloaded '""' method with the following code (line 157 of "IO/" file): use overload '""' => sub { $_[0]->opened ? ${$_[0]->sref} : 'undef' }; I would very much appreciate if this problem could be addressed in the next version of this excellent package. Many thanks! Best regards, Pawel Krol.
