I'm having few problems with that approach, (asdf:load-system :craftd) with that safe eval doesn't work at all, pretty printing the error gives #<a UNDEFINED-FUNCTION>. I'm pretty new to LISP so bear with my noobness please. > Have you tried moving those calls inside cdcl_EventDispatcher ? > From > https://github.com/meh/craftd/blob/master/scripting/lisp/main.c > I do not really see that those functions are called from the main thread > under equal conditions (stack depth, memory, etc). This may perturb the > garbage collector. If I put the thread stuff in cdcl_EventDispatcher I get a segfault on ecl_release_current_thread(). Here's the backtrace with ecl in debug mode if it can be of any help. It's clearly receiving a NULL lock for some kind of reason. > Program received signal SIGSEGV, Segmentation fault. > [Switching to Thread 0x7ffff7fce700 (LWP 7814)] > 0x00007fffef6d3de0 in mp_giveup_lock (lock=0x0) at > /var/tmp/portage/dev-lisp/ecls-11.1.1-r1/work/ecl-11.1.1/build/ecl/object.h:1055 > 1055 > /var/tmp/portage/dev-lisp/ecls-11.1.1-r1/work/ecl-11.1.1/build/ecl/object.h: > No such file or directory. > in > /var/tmp/portage/dev-lisp/ecls-11.1.1-r1/work/ecl-11.1.1/build/ecl/object.h > (gdb) bt > #0 0x00007fffef6d3de0 in mp_giveup_lock (lock=0x0) at > /var/tmp/portage/dev-lisp/ecls-11.1.1-r1/work/ecl-11.1.1/build/ecl/object.h:1055 > #1 0x00007fffef6d3181 in thread_cleanup (aux=<value optimized out>) at > /var/tmp/portage/dev-lisp/ecls-11.1.1-r1/work/ecl-11.1.1/src/c/threads/process.d:130 > #2 0x00007fffef6d38d9 in ecl_release_current_thread () at > /var/tmp/portage/dev-lisp/ecls-11.1.1-r1/work/ecl-11.1.1/src/c/threads/process.d:284 Thanks, meh. ------------------------------------------------------------------------------ Xperia(TM) PLAY It's a major breakthrough.
