in reply to Strange AUTOLOAD's bevavior with utf8 data

FWIW (I currently don't have 5.8.9 available), I've just tried it with 5.8.8 (x86_64-linux-gnu-thread-multi) and 5.10.0 (x86_64-linux) and 

$body = "This \x{5555} is \x{6666} a \x{7777} test\n";

and it prints out fine (immediately).  Of course, that won't help much if it's a 5.8.9-specific issue...

Could you post a specific UTF-8 string that reproduces the problem in your case with the code as shown? (BTW, I had to put in a use Carp for the croak)

    Thanks for your reply.

    I've looked at my code again before posting here full module source and found string in my AUTOLOAD sub that stoped my app:

    carp "value now is ".$value;
# ..this message will not be printed if $value is utf8 string

    [download]

    So I found the real error source: combination carp & use diagnostics

    Can you check following code in your environment?:

    #!/usr/bin/perl

use strict;
#use diagnostics; # when uncommented will freeze the app
use Carp;

print "before carp\n";
carp "\x{41f}\x{440}\x{438}\x{432}\x{435}\x{442}"; #'Hello' in Russian
print "after carp\n";

    Is this a normal reaction on "use diagnostics"?

      I tried it on

      • Debian Linux 5.8.8
      • ActivePerl Windown 5.6.0
      • ActivePerl Windown 5.6.1
      • ActivePerl Windown 5.8.0
      • ActivePerl Windown 5.8.8
      • ActivePerl Windown 5.8.9
      • ActivePerl Windown 5.10.0

      With 5.8.8 and 5.8.9 in Windows, I get a 4 second "pause" where CPU activity reached 100%.

      It doesn't occur with warnings and without diagnostics (a debugging tool) and it doesn't happen in 5.10, so it's a non-issue.
