Nick Gravgaard (Sep 29 2022 at 14:57): Nick Gravgaard (Sep 29 2022 at 14:57):I've just installed the latest Ubuntu on a VirtualBox host, and used shared folders to copy across the latest nightly build archive of roc and my recently cloned roc repo.
Building the repo's examples/gui/Hello.roc using the roc binary from the archive file results in an error.

This does however create a hello-gui file which successfully opens a window when run. When I close that window a Segmentation fault (core dumped) message appears in the console.
I was just about to create a GitHub issue but thought I should ask here first. Any ideas?
