Package: gprolog Version: 1.4.5-4.1+b1 Severity: grave Justification: renders package unusable
Hi, Something seems to be very wrong with gprolog on amd64. Consider this trivial Prolog code: parent(david, john). parent(jim, david). grandparent(A, B) :- parent(A, X), parent(X, B). When I try to use this program, I get a strange exception. This happens on amd64 but not on i386. $ gprolog GNU Prolog 1.4.5 (64 bits) Compiled Feb 5 2017, 10:30:08 with gcc By Daniel Diaz Copyright (C) 1999-2016 Daniel Diaz | ?- consult(family). compiling /tmp/family.pl for byte code... /tmp/family.pl compiled, 3 lines read - 644 bytes written, 2 ms yes | ?- grandparent(jim, X). uncaught exception: error(existence_error(procedure,parent/0),grandparent/0) | ?- -- System Information: Debian Release: 9.0 APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.9.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=nl_BE.UTF-8, LC_CTYPE=nl_BE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages gprolog depends on: ii libc6 2.24-10 gprolog recommends no packages. gprolog suggests no packages. -- no debconf information
