This is a bug report for perl from wangxz00@mails.tsinghua.edu.cn,
generated with the help of perlbug 1.35 running under perl v5.8.6.


-----------------------------------------------------------------
[Please enter your report here]
When using split() function in (??{...}), the Perl interpreter died.
This error can be verified by the following program:
#!/usr/bin/perl
$a="aba";
print "matched\n" if $a=~/(??{"aba"})/;	# OK
print "matched\n" if $a=~/(??{join("",split("","aba"))})/; # Segmentation Fault

[Please do not change anything below this line]
