Yes, because macOS 13 build fails. I've skip it with hope that macOS 11 and 
macOS 12 pass. No, it doesn't.

My guess that this machine has very limited amount of RAM (14 Gb if I not 
mistaken) and simple can't build it, thus using of GCL_MEM_MULTIPLE leads to a 
crash.

As a dirty hack, to make it works, I've tried this patch:

but it doesn't help.

Anyway, as soon as we stabilise build on my laptop which has a lot of RAM, I'll 
try to reproduce this issue on VM with less memory.

Yes, I have suceffuly build it on my laptop via `port build` which is used on 
Github CI, but it fails outside of MacPorts and on CI as well.

Unfortunately no, you may fork this repository and push to your fork and use 
github CI to build it, but without any SSH access.

So, old school print debugging :(
