Re: memory problem when compiling list of lists

[Erick Alphonse]

Hello,

I want to update an old report on memory consumption problems in gprolog.

I have attached the file to consult (6Ko uncompressed). Gprolog 1.2.18 
has the same problem.

Also, I cannot load files containing clauses of about 24Mo. gprolog 
cannot load them and asks for more than GLOBALSZ=800Mo and 
TRAILSZ=100Mo. I hope the bugs are related.

Did someone experience the same problem? I would be very grateful if 
someone could send me a workaround or a patch for these problems. I 
really need to run some experiments ;-).

Thanks a lot in advance,
Best regards,
Erick.
