Almost 4 million lines (possibly more) on a FreeBSD 5.4 with a
default Perl install of 5.8.7, and 30 million on a Linux.
[talking about the following test case:
perl -e '$hdr="to"; $h="To:"; $h.=" [EMAIL PROTECTED]" for (1..4000000/3);
$h=$h.$h."From: bla to: me\n".$h;
@a=$h=~/^\Q$hdr\E:[ \t]+(.*?\n(?![ \t]))/smgi; printf("%d\n",scalar(@a))'
]
Btw, I'm assuming the $hdr is not supposed to be a regular expression,
but a plain string, for which \Q...\E quoting is more appropriate.
