Faulting application perl.exe, version 0.0.0.0, faulting module msvcrt.dll, version 7.0.2600.1106, fault address 0x0003334c.

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Can you reproduce this error? Or fix it? It only happens under taint. Editing either the html/codefile can make the error disappear (similar to disappearing segfault). I've reproduced this on activeperl5.8.9, strawberry5.10, and perl v5.11.0 I compiled myself

perl -T taintbug.pl file:http.taint.html

#!/usr/bin/perl -- --
# without Taint there is no bug


use strict;
use warnings;

warn "THIS REPLICATES THE BUG\n";warn $_ for %INC;

{
    
#NOBUG without $ua                      ##### # # # # 
    use WWW::Mechanize;
    my $ua = WWW::Mechanize->new();

    my $url = shift;

    die "NoBug WO file:httpbug.htm"
        unless $url and length $url and $url =~ m!http.*?(\w).(\w)!i ;

    $ua->get($url);

    my $pager = parsepage($ua);
    warn;
}
exit(0);

sub parsepage {
    my $ua = shift;
    my %so;
    my $so = join "\n", $ua->content =~/(so\.addVariable\(\s*'.+?'\s*,
+\s*'.+?'\s*\)\s*;)/mg;
    warn $so;
    warn; #    Insecure dependency in kill while running with -T switc

Very similar problem but with Faulting application perl.exe, version 0.0.0.0, faulting module perl514.dll, version 0.0.0.0, fault address 0x0006f0eb. The program `#!/usr/bin/perl -- use strict; use warnings; use File::Slurp; my @junk = ("junk") x 15; for my $f ( @junk ){ my( $what, $junk ) = split /whatever/, scalar read_file( $f ); }` [download] The error goes away if you split a variable, say $f. It also doesn't happen with ActivePerl-5.14.2.1402-MSWin32-x86-295342. Is this bug important, I don't know :/ File::Slurp 9999.19 and perl 5.14.1 perl -V Read more... (3 kB)	[reply] [d/l] [select]
