This is a bug report for perl from query1000@gmail.com,
generated with the help of perlbug 1.36 running under perl 5.10.0.


-----------------------------------------------------------------
[Please enter your report here]
Type following script and save it with UTF-8, and run with Perl 5.10.0 and
Windows XP SP2 DOS BOX.
The DOS BOX will be frozen.

Some how the filename of the program matters with the phenomenon.

I saved the program as;
 C:\Documents and Settings\fuc\へなだべぴよ\test\test.pl
(へなだべぴよ is Japanese pathname Desktop)
and run it as following command;
 C:\> cd Documents and Settings\fuc\へなだべぴよ
 C:\Documents and Settings\fuc\へなだべぴよ\> .\test.pl
and it will cause the freeze.

 But when I saved the program as;
 C:\Documents and Settings\fuc\へなだべぴよ\test\bug.pl
and run it as following command;
 C:\> cd Documents and Settings\fuc\へなだべぴよ
 C:\Documents and Settings\fuc\へなだべぴよ\> .\bug.pl
and it WON'T cause the freeze.

Thank you !

#! /bin/perl -w
#
# if you run this program wirh ActivePerl 5.10.0 and Windows XP, the Dos Box
will be frozen
