FWIW, it appears that guile-1.9.5 does not work with the default bdw-gc in ubuntu/debian, which is gc-6.8 -- I got the crash below downloading, compiling, installing gc-7.1 seems to fix the problem. BTW, I am vaguely thinking of using bdw-gc for my code, which links to guile .. will this be a problem ?? --linas =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D a crash, when evaluating (+ 1 1) I believe that this is another threading bug -- my app loads a number of scm files during startup, and then starts an interactive shell. The crash occurs in the shell, with the following stack trace: #0 0xf73fbce5 in GC_local_malloc () from /usr/lib/libgc.so.1 #1 0xf7d53ca3 in scm_gc_malloc (size=3D348, what=3D0xf7df6634 "thread") at gc-malloc.c:200 #2 0xf7db453c in guilify_self_1 (base=3D0xf54a49dc) at threads.c:326 #3 0xf7db633d in scm_i_init_thread_for_guile (base=3D0xf54a49dc, parent=3D0xa293af0) at threads.c:593 #4 0xf7db6545 in scm_i_with_guile_and_parent (func=3D0xf7c56180 , data=3D0xa2167d8, parent=3D0xa293af0) at threads.c:732 #5 0xf7db668e in scm_with_guile (func=3D0xf7c56180 , data=3D0xa2167d8) at threads.c:715 #6 0xf7c564ba in opencog::SchemeEval::eval (this=3D0xa2167d8, expr=3D@0xf5= 4a4a6c) at /home/linas/src/novamente/src/opencog-embodiment/opencog/guile/Schem= eEval.cc:460 FWIW, the above was built against gc-6.8, which is what ubuntu and debian come with. Suspecting that this is a gc problem, I downloaded, compiled, installed gc-7.1 and went to rebuild guile. .... it works! --linas
