I was going to experiment with places for parallelism and I have compiled from source to support it. Then I've encountered a very strange bug that does not happen with 5.1
;;test.rkt #lang racket (require "def.rkt") (displayln dyn-def) ;;def.rkt #lang racket (require racket/runtime-path) (provide dyn-def) (define-runtime-path dyn-def "logs/") Running the test.rkt module it sometimes shows this error, with no indication of its source: make-vector: expected argument of type <non-negative exact integer>; given 693450754. The number varies, and the error happens usually after 5~10 runs. I have compiled the latest git version like this mkdir racket-places cd racket-places ../src/configure --enable-places --prefix=/usr/racket-5.1.0.2-with-places make sudo make install I end up with version 5.1.0.2--2011-02-05(-/f) [3m]. Any ideas? -- Eduardo Bellani omnia mutantur, nihil interit. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
