Comment (by Dave-Allured):

 Here is a more reduced demo for the `setfileoption` bug:

 {{{
 procedure test3 ()
 begin
   setfileoption ("nc", "Format", "Classic")
   x = 99
   print (x+"")
 end

 begin
   test3 ()
 end
 }}}

 This should just print "99" if NCL is working correctly.  With current
 build ncarg.6.4.0_9 it gets this error, which is equivalent to the
 previously reported errors:

 {{{
 > ncl test3.setfileoption.ncl
  NCAR Command Language Version 6.4.0
 fatal:Variable (x) is undefined
 fatal:["Execute.c":8640]:Execute: Error occurred at or near line 5 in file
 test3.setfileoption.ncl
 fatal:["Execute.c":8640]:Execute: Error occurred at or near line 9 in file
 test3.setfileoption.ncl
 }}}

 The previous test script, bar.ncl, is longer than needed, and it contains
 an unrelated bug that can also corrupt NCL execution and print more
 confusing errors.  The problem is a missing "undef" statement at the top,
 not related to the current issue.

 I agree with Takeshi's previous observation that `setfileoption` appears
 to break the symbol table.
