It's a problem with closures in current versions of perl. Named subs (such as END) don't close on behalf of inner anonymous subs (such as the try block effectively is), so the variable goes out of scope before END is called. The presence of the variable directly in the END sub causes the variable to be captured and thus live long enough for END to be called. It's already fixed (by me :-) in the development branch of perl: 
$ cat /tmp/p
#!/usr/bin/perl -w

my $x = 1;
END {
    sub { print "x=$x\n" }->();
}
$ perl586 /tmp/p
Use of uninitialized value in concatenation (.) or string at /tmp/p li
+ne 5.
x=
$ perl590 /tmp/p
x=1
$
