As has already been noted, perl level 41 fails the test.  There seems to be
a problem with the cmp operator and possibly the || op as well.
I distilled the failing test down to the following test cases.  I think this
illustrates the problem.  Unfortunately I am not a Perl internals hacker
so I can't go any further.  I am great at getting test cases though.

Perl Script follows:
#!/bin/perl
print (-123 cmp ',');
print "\n";
print (0||516);
print "\n";
print (-123 cmp -124);
print "\n";


This script print out the following:
712
516
-26876

Now unless I am wrong, cmp should only ever return -1, 0 or 1 and isn't that 
supposed to be true of ||?  It is clear that the bigint lib depends on 
cmp only returning 0, -1 or 1.
