I have uploaded SWI-Prolog 7.1.14. Most of the changes fix possible crashes, notable in the semweb (RDF) library. Thanks to Wouter Beek for trying to download all data from the `Linked Open Data cloud' and processing them in threads using RDF transactions ... Other stuff:

• Two patches for the Dict.key syntax (unbound key, Dict is a list)
• Serious bug in variant_sha1/2, returning same hash for all `indirect' datatypes (float, big int, string).
• Fixed portability to 32-bit platforms that have no support for 64-bit atomic operations (e.g., (some?) ARM).
