guile fibers crashing on M3 airbook (Mac15,12) using guile-next

[dannyob]

(This also means that guile goblins doesn't work)

I've included the versions and lldb dump below. Hope that helps, happy to help more!

Thanks for all your work,

@dannyob thank you for reporting this and for the sponsor ❤️ ! i'll take a look as soon as i can. I was on vacation for a couple of weeks and just catching up with work and others.

No hurry! One thing I noticed was downloading and building guile-fibers from scratch on my Mac worked fine. Not sure which compiler it was using, but I can find out if it is useful to you!

Hi! I checked (and actually pushed a new guile-next) and could reproduce the issue. I believe the .go files should be compatible between versions so not sure what's going on. I will ask the guile-user mailing list and see what they say.
