Uh this is funny:
(open-output-file '(|path:| "test.flog" |create:| maybe |append:| #t))
look there, there's |:s around the keywords. This means they're *not* actually keywords but *symbols* that kind of look like keywords.
I suppose this is the cause of the error you encountered.
Tried to reproduce your error on 4.6.2:
$ cat a.scm (write (cons abcde: 123)) $ gsi a.scm (abcde: . 123)$ gsc -exe a.scm $ ./a (abcde: . 123)
I.e. does not reproduce your results. Not one character of the involved Gambit code ought to have been changed in the current version since 4.6.2.
Do you compile this code just with gsc filename.scm or (compile-file "filename.scm") or do you have some preprocessor on it?
Do you see any other reasons for why this occured?

With Gambit 4.6.6, I am seeing decidedly different behavior for open-output-file between code compiled with gsc/gcc to run as a standalone executable and that same code compiled with gsc to run under gsi. The source code follows the body of the message, but the error from the standalone run tells the whole story, really. Specifically:
drr@dibbuk$ make target=gambit test/bug.gambit gsc -:s -link test/bug.Gambit gcc -I/home/drr/include test/bug.c test/bug_.c -o test/bug.gambit \ -L/home/drr/lib -lgambc -lm -lutil -ldl drr@dibbuk$ test/bug.gambit *** ERROR IN flog-file -- (Argument 1) STRING or port settings expected (open-output-file '(|path:| "test.flog" |create:| maybe |append:| #t))
drr@dibbuk$ gsc test/bug.Gambit drr@dibbuk$ gsi Gambit v4.6.6
(load "test/bug")
"/home/drr/git/heureka/framework/test/bug.o2"
(main (vector "this is a test")) (exit)
drr@dibbuk$ cat test.flog this is a test this is a test
Now the repeated lines in test.flog are expected from the gsi case because the code is effectively run twice, once upon load and once manually (as will be seen from the source below). So what is going on with the standalone execution? I am very puzzled.
the source code for bug.Gambit. This is the output of a preprocessor, so it looks a little strange, but it is really very straightforward.
(define _cons_23 cons) (define *flog-use-current-output-port* #f) (define *flog-use-current-error-port* #f)
(define flog-file (lambda (_file-name_38 _s_39) ((lambda (_f_40) (begin (display _s_39 _f_40) (newline _f_40) (if *flog-use-current-output-port* (display _s_39 (current-output-port))) (if *flog-use-current-error-port* (display _s_39 (current-error-port))) (close-output-port _f_40))) (open-output-file (_cons_23 (quote path:) (_cons_23 _file-name_38 (quote (create: maybe append: #t))))))))
(define main (lambda (_argv_38) (begin (flog-file "test.flog" "this is a test") )))
