Details:


Tested to occur in Octave versions:

- 3.6.1+ (000cd393f3c1),
- default (6a736395ff7d).

Description:

Accessing variables in some type of recursion gives wrong values if some
(unrelated) handle to a private function was set.

Repeat by:

- Copy attached 'testfunction.m' into current directory,

- copy attached '__dummy_private_function__.m' into subdirectory '/private',

- start Octave freshly,

- run 'testfunction',

- from the debug prompt, enter v to see its value.

The bug shows up if you see a value of '2' for 'v', although you are in the
body of an 'if' statement which tests for v==1. (The non-interactive 'printf'
before has printed a value of '1' for 'v').

If you comment out the line in 'testfunction.m' which sets the handle to
'__dummy_private_function__', the bug will not occur. Also, the bug only seems
to occur in the first call to 'testfunction'.
