Description
When a source file contains an atom whose length is larger than 255 characters, B-Prolog 8.1 apparently succeeds in loading the file when in fact the file contents fails to be loaded into memory.

Research direction
Start by reproducing the reported behavior in B-Prolog 8.1 with a source file containing an atom longer than 255 characters, then verify whether loading actually populates memory. The issue is done when the failure is reported clearly or the file contents are loaded correctly rather than silently ignored.
