I figured out why the B::XXXX::METHODS were causing page faults. It was a case of user error. <sheepish grin>

One must pass an object from the appropriate class to them or that will happen. For example, to use B::PVLV::TYPE you have to pass an object of the B::PVLV class to it.

use B;
my $lvalue = \substr("abc",1,1);
my $lvobject = B::svref_2object($lvalue);
print B::PVLV::TYPE($lvobject);

Had I read the item about B::svref_2object I would have known this.
