Hi, I believe there is something wrong with the VM setup for Guile as it always produces the same SIGABRT error regardless of the program. I tried a hello world program, I tried an empty project, and I tried copy and pasting a valid solution for FLOW001, but every one of these returned a runtime error (EDIT: The error is “Wrong __data_start/_end pair”). If I’m doing something wrong, I’d definitely like to know, but to me it seems like a problem with the service.
