Hi folks,

I was using Emacs and encountered a crash.

I am running on macOS, and I built Emacs from scratch/igc using the
instructions on that branch.

I didn’t have Emacs running under a debugger, but I do have some crash
information captured by macOS. (See attached.)

At the time, I was trying to use apropos-documentation. I invoked the
command once, entered a string, and hit RET, and it signaled an error. I
tried to do this again and Emacs crashed.

I hope this is useful. Please let me know if there’s any other
information I can collect.

Thanks!

Looks to me like apropos-safe-documentation, native compiled, has a
problem here and gets an EXC_BAD_ACCESS. But that's all I can see. It's
not even clear to me if this is GC-related or not.

Can you reproduce this? If yes, can you give me a recipe?

Pip, should I perhaps merge with current master? I think there have been
fixes to the native compiler on master, not sure though.
