memory problem when compiling list of lists

Hello,

The file bug.pl contains a fact declaring a list of lists. When 
consulting this file, gprolog (pl2wam) requires a large amount of 
memory, and the longer the list, the higher the memory. Consulting a 
list of more than 1000 lists requires more than 200Mo. The file is 
successfully compiled under eclipse.
