Re: warning: perl bug in 5.6.x, Win32 (use warnings and STDERR)

in reply to warning: perl bug in 5.6.x, Win32 (use warnings and STDERR)

Not really. Try

open(ME, "$0") or die "crap $!";

close(STDERR);
use warnings;


while (<ME>) {
    print;
}
close ME;

So it would appear there is a bug only if you close(STDERR); and use warnings; before you do a open.

This definetly warrants a look-see by the perl 5 porters (p5p).

I tried to play with this a little more. It only prints the first line even if you remove the use warnings and run the script with perl -w or if you set the $^W.

close(STDERR);
open(ME, "$0");
$^W=1;
while (<ME>) {
    print;
}
close ME;

It fails even if you put the $^W=1; inside the loop, but you always have to close the STDERR before opening the file.
