Memory fault when starting on macOS Mojave + SBCL 1.5.3

[VitoVan]

Seems like a interesting game, but I haven't been able to play it yet.

I tried download the binary from https://vydd.itch.io/qelt , it will hang when starting.

Would these information be useful?

I get the same memory error on macOS Catalina using SBCL 2.1.6.

With the executable, it crashes immediately showing only a white rectangle in the opened window.

I tried to run it from source and got to the next screen after the starting screen, which looks like this:

Then it crashes too logging the memory error. Maybe this helps if you want to attempt fixing it someday. Looks like a nice game to show what can be done with Sketch!
