Hmmm, both this code: 
#!/usr/bin/perl
my $s = "<object>" x 1600_000; #made higher to be sure
die("Failed validation!") unless $s =~ /^(?:<object>)+$/;
print "ok\n";

And your command line example run fine (well, both print "ok") on perl, v5.8.3 built for i386-linux-thread-multi - that's the debian "testing" package, and perl, v5.8.4 built for i386-linux-thread-multi (that's debian "unstable")
