ok, I got a segfault in a program and I don't quite understand the cause.
Your code is using %string-charset->pred which you don't specify in your mail. You could run Gambit under gdb. This usually gives hints. BTW are you using (declare (not safe)) ? I think print (define-prim (print #!key (port (macro-absent-obj)) #!rest body) (macro-force-vars (port) (let ((p (if (##eq? port (macro-absent-obj)) (macro-current-output-port) port))) (macro-check-output-port p 2 (print port: p . body) (##display body p))))) whereas (define-prim (##display obj port #!optional (max-length ##max-fixnum)) (if (macro-character-output-port? port) (begin (##write-generic-to-character-port 'display port (macro-character-port-output-readtable port) (macro-if-forces #t #f) max-length obj) (##void)) ((macro-port-write-datum port) port obj #f))) so I don't really see why choosing one over the other should matter.
