multiple BNODE() calls result in not distict blank nodes (not SPARQL 1.1 standard compliant)

[jmkeil]

The query ASK { FILTER (BNODE() = BNODE()) } (try) returns true on Virtuoso version 08.03.3330 (879a32f2c3).

According to the standard, it should return false:

If the no argument form is used, every call results in a distinct blank node.
