     Type:  defect       |      Status:  new  
 Priority:  major        |   Milestone:       
Component:  extensions   |     Version:  4.2.x
 Keywords:  srfi-19      |  
-------------------------+--------------------------------------------------
 csi -R srfi-19
 (format-date #t "~Y")
 Segmentation fault

 csi -R srfi-19
 (format-date #t "~Y")
 Segmentation fault

 This typically dumps users back from the REPL to the shell command line,
 losing their session.  If this is encountered in compiled code, the
 program bails without explanation.

 An error should be raised saying that the date object must be specified.

 Also:
 csi -R srfi-19
 (format-date #t "")
 Error: (get-output-string) argument is not a string-output-port: #<output
 port "(stdout)">

 An error should be raised saying that the date object must be specified or
 that the format string is empty.

 csi -R srfi-19
 (format-date #t "~Y" (make-date 0 2 1 13 10 11 2009 0))
 Error: (get-output-string) argument is not a string-output-port: #<output
 port "(stdout)">

 The same happens if an output port is given instead of #t

 According to the online documentation for the SRFI-19 egg, this procedure
 call should write the formatted date to (current-output-port) or to the
 specified port.
