This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.28 running under perl v5.6.0.
-----------------------------------------------------------------
The following script was run under Perl 5.004_04, 5.6.0 and
5.6.1 TRIAL 1
##Start
$x="20010103.09:04:10: single line\n";
print "** with spaces:\n";
if ($x=~/[0-9]{6}\.[0-2][0-9]:([0-5][0-9]:){2} single line\n/) {
print "matched\n";
} else {
print "no match? gee, this is really borken\n";
}
print "** with whitespace control char:\n";
if ($x=~/[0-9]{6}\.[0-2][0-9]:([0-5][0-9]:){2}\ssingle\sline\n/) {
print "matched\n";
} else {
print "no match? gee, this is really borken\n";
}
##End
Under 5.6.0, the regexp is not matched when using literal whitespace
instead of whitespace control characters. This problem does not
occur in 5.004_04 or 5.6.1 trial 1:
Results for your examination:
5.004_04:

Furthermore, look what happens with these two scripts that
attempt to match across lines (/s qualifier) under 5.6.0. You'll
see why I had to break it up:
$x="multi line...20010103.09:46:25: multi
: line
";
print "** with whitespace control char:\n";
if ($x=~/[0-9]{6}\.[0-2][0-9]:([0-5][0-9]:){2}\smulti\n {17}: line\n/s) {
print "matched\n";
} else {
print "no match? Gee, this is borken!\n";

Out of memory during ridiculously large request at p2 line 6.
Note that there is whitespace before the {17} and the 'line\n' text that works
fine.
It looks like the whitespace that follows a {} count specifier may be the
problem.
