Hello CHICKEN users! I'm using CHICKEN 4.13.0 from 2017 December. When debugging why "send eof" caused our server to hang indefinitely, I found out that utf8's string-length was the culprit:
``` $ csi (use utf8) (string-length "\377\354") ; line that was read from send eof ;; hangs ``` causes the interpreter to hang at least 30 seconds, probably indefinitely. I understand that this string isn't a valid UTF-8 codepoint, but does anyone have suggestions for what to do here? (E.g., "Upgrade to CHICKEN 5" would be a nice answer.) Some more results that make me think the \377 octal code in particular is culpable: ``` #;4> (string-length "\354 a") 1 ; OK, since \354 isn't a valid UTF-8 char #;5> (string-length "\366 a") 1 #;6> (string-length "\377 a") ;; Hangs ``` Thank you, Henry Infolab Group @ MIT Cambridge, MA USA
