[perl #21298] Perl SIGSEGV when applying regular expression to a long string

This is a bug report for perl from t-perl@snowelm.com,
generated with the help of perlbug 1.34 running under perl v5.8.0.


-----------------------------------------------------------------
[Please enter your report here]

The attached perl script, which applies a regular expression to
a long string, causes Segmentation Fault on my Debian GNU/Linux 
system.

Although the script contains some Japanese 2-byte characters, 
LANG environmental variable seems unrelated to the bug. 
Sorry for the lengthy example, but the length of the string
seems important to cause the bug.

Since the script is a part of a CGI script, it took a very 
long time to find out that the reason is perl SIGSEGV.  I'd
appreciate very much if you could fix perl to display some
error message rather than SIGSEGV.
It is no need to provide a workaround for the bug to me,
because I already have one.

Thank you very much for developing Perl!

Best regards,
Makino Takaki
