The openpsi `README.md` also has description: OpenPsi examples - The examples [here](https://github.com/opencog/opencog/tree/master/examples/openpsi) are currently broken. The openpsi examples needs to be updated as well.

There are two threads. The first is where Python runs its code and the second which is run by OpenPsi. OpenPsi thread calls Python method `eat_apple(apple)` using GroundedSchema. Python thread...

Here is the stack trace from `LD_PRELOAD=/lib/x86_64-linux-gnu/libSegFault.so guile samples/ghost/sample-ghost-notebook.scm` ``` [2019-04-26 15:28:46:364] [WARN] [GHOST] Did you forget to link a goal to the rule? [2019-04-26 15:28:46:399] [WARN] [GHOST] Did you...

> I'm guessing that ghost starts one or more threads. So, `ghost-halt` should call `join-thread` on every thread that it starts. I prepared the suggested fix #3487 It also requires...

> @stellarspot, just want to make sure, are you getting this segfault only when exiting Guile when the loop was still running? Or does it crash even without exiting Guile?...

I see it works with the fix #3485 if test-ghost is used: ```scheme (use-modules (opencog) (opencog nlp) (opencog nlp relex2logic) (opencog openpsi) (opencog ghost) (opencog ghost procedures) (opencog exec) )...

I see. Thank you. If I add the `(sleep 1)` before the ghost-halt it works.

There is one more example where pattern `r: (* work in _*) '_0 is a great company!` does not generalize to `Alice works in HardMegaCorp.`. So it works with `I...

The message "c++: internal compiler error: Killed (program cc1plus)" in the cogutil CircleCI build could mean that there are no enough memory or swap space on the system and it...
