[Philip Nienhuis]

Update of bug #37804 (project octave):

              Item Group:                    None => Regression             
                  Status:                    None => Confirmed              
                 Release:                   3.6.3 => dev                    
        Operating System:               GNU/Linux => Any

Follow-up Comment #1:

Tested some more versions.

It also crashes on Windows (MSVC2010 & MinGW):


octave-3.6.2.exe:1> a = 1
a =  1
octave-3.6.2.exe:2> b = 2
b =  2
octave-3.6.2.exe:3> a{~}.b
parse error:

  invalid use of empty argument (~) in index expression

>>> a{~}.b
       ^

panic: Segmentation violation -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete


Could be provoked on Octave-3.4.3MinGW (one but oldest I have installed) as
well, but in Octave MinGW-3.2.4:


octave-3.2.4.exe:1> a = 1
a =  1
octave-3.2.4.exe:2> b = 2
b =  2
octave-3.2.4.exe:3> a{!}.b
parse error:

  syntax error

>>> a{!}.b
       ^

octave-3.2.4.exe:3> a
a =  1
octave-3.2.4.exe:4> b
b =  2
octave-3.2.4.exe:5>


...no crash occurs, so this is a regression.

(Status changed to "Confirmed", OS to "Any", Item Group to "Regression")
