"function" function -- infinite loops and bus error [not user problem] (PR#361)

Mon, Dec 6, 1999 3:19 AM

The following is in "all" versions of R,
but is not really a bug that users will stumble about.

Still should be fixed 
(making sure that performance is not degraded by the fix ..)


 f <- get("function")

 f(,) ##-- gives INFINITE loop; breakable with <ctrl> c.
 f(NULL,)# [and other variants] as well

 f(F,F)

 >> Bus error  and R is killed.
