The forth interpreter isn't completely busted, my test.f screenshot above worked. A simple "echo ascii values" program I wrote ( BEGIN KEY DUP . CR 0< UNTIL ) worked. But my 32 line, mildly more sophisticated program just… signal 11s. I do not know how to proceed. I am using "Debian Testing", which is TECHNICALLY a beta OS, so maybe the pforth is broken *subtly*. gforth isn't in dpkg. I don't… I don't know what to do next if the compiler crashes.
Maybe I ssh into a VPS and run gforth there? :(
