Bug report for Octave 2.1.10 configured for %CANONICAL_HOST_TYPE%

Description:
-----------

Problem in parsing m-file with unclosed for loop inside a switch:
edalf:/S4/hodel/oct $ octave
Octave, version 2.1.10 (alphaev56-dec-osf4.0b).

octave:1> errtest.m
parse error near line 7 of file /S4/hodel/oct/errtest.m

>>>   endswitch
              ^

panic: impossible state reached in file `parse.y' at line 1435
error: IOT/Abort trap -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Resources lost(coredump)

Repeat-By:
---------
File errtest.m:
for ii=1:3
  switch(ii)
  case(1),
    printf("Hello ");
    for kk=1:4
      kk
  endswitch
endfor

Fix:
---

  unknown; correct behavior is to report for loop closed by endswitch
  and return to octave prompt.  [Since I'm working with 2.1.10,
  this may be repaired in later versions.]
