that produces eof

which makes sense, the fasl is empty

but how did it get that way?

This is weird, why do we have another start of racket/fasl in there, right after the null chars

@cadr after several iterations of compiling, I’m now at: │········································· [samth@huor:~/sw/pycket (master) plt] pk -l racket/contract/private/out │········································· module-prefetch: (private/define-config.rkt setup/dirs) in: #<path:/home/samth/sw/plt/racket/coll│········································· ects/planet/> │········································· module-prefetch: (rand.rkt generate-base.rkt guts.rkt prop.rkt racket/list) in: #<path:/home/samt│········································· h/sw/plt/racket/collects/racket/contract/private/> │········································· exn:fail : Reference to an undefined variable : multi-exercise12.1

so that might be an easier way to reproduce the missing export bug

current fixed point is 34 failures
