Hello everyone, I just came to this bug. Assume that I have a prolog file "fatal_error.pl", which contains a( [ b(c), b(c), b(c), … b(c) ] ). If I consult the file | ?- [fatal_error]. compiling /Dvlpt/trfmodels/fatal_error.pl for byte code... /Dvlpt/trfmodels/fatal_error.pl compiled, 261 lines read - 26473 bytes written, 761 ms (3 ms) yes If there were less than 257 b(c) compound statements, I have no problem retrieving the knowledge: | ?- a(R). R = [b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c)] Yes If there are 257 b(c) compound statements or more, gprolog crashes: GNU Prolog 1.4.4 (64 bits) Compiled Jun 3 2014, 17:40:55 with gcc By Daniel Diaz Copyright (C) 1999-2013 Daniel Diaz | ?- [fatal_error]. compiling /Dvlpt/trfmodels/fatal_error.pl for byte code... /Dvlpt/trfmodels/fatal_error.pl compiled, 261 lines read - 26473 bytes written, 761 ms (3 ms) yes | ?- a(R). cannot display cyclic term for R (1 ms) yes Fatal Error: Segmentation Violation (bad address: 0x803) The same happens in 1.4.0, in 1.4.4 and the latest unstable version from 20140207.
