Is this a gplc bug or something in my code? How to diagnose? I looked into the related Prolog file but its contents seem fine (it defines a single multifile, dynamic predicate).

After some more experimentation, I found that the error can be avoided by having a single initialization/1 directive in the Prolog file (the original file had three initialization/1 directives, which is not usual but still standards compliant).

Cheers,
