Sorry for the extreme delay in replying.

Does this problem still manifest in the latest Guile-SDL
(version 0.6.1, 2022-02-20)?

It looks like the REGISTER_KP_V macro called register_kf_v() for some reason, which can only mean that the register_kp_v pointer is set wrong in the obtw struct.

Woops. My mistake. It should be initialized.

OP here, now with an account.

It looks like this happens in make_flagstash().
It looks like make_flagstash() will always segfault as I can see no way that stash->val is ever going to be initialized.

This would seem to imply that make_flagstash is never called in testing which also sounds like a test coverage issue.

The only thing I can think of that would be different is the bash environment but I'm not entirely sure what is changed in the testing environment. Especially not anything that would cause a segfault.
