This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.35 running under perl v5.8.7.
-----------------------------------------------------------------
[Please enter your report here]
The LAST_REGEXP_CODE_RESULT ($^R) variable appears to not be set
in regexp matches involving a backreference. In the example below,
if you uncomment one of the two commented regexps and comment the
'(foo|bar)\1+' regexp, $^R will be properly set.
#! perl -w
# $^R undefined on matches involving backreferences
use strict;
print $^R, "\n" if 'x foofoo y' =~ m{
# (foo) # $^R correctly set
# (?:foo|bar)+ # $^R correctly set
(foo|bar)\1+ # $^R undefined
(?{ warn "Matched", defined $^N? " <$^N>":"",
" and \$^R is about to be set to:\n"; "last regexp code result"
})
}x
Hope that helps,
Dan Dascalescu
