tests working on first run of __run_test_suite__ failing second time around

[c.]

Hi,

If I do "test ctor-vs-method.tst" no matter how many times I try, it always 
passes:

>> test ctor-vs-method.tst 
PASSES 4 out of 4 tests
>> test ctor-vs-method.tst 
PASSES 4 out of 4 tests
...

If I run __run_test_suite__ once, I get:

ctor-vs-method.tst ..................................... PASS    4/4

the second time I get:

ctor-vs-method.tst ..................................... PASS    1/4    FAIL 3

if, after that, I do "test ctor-vs-method.tst", I get:

>> test ctor-vs-method.tst 
  ***** shared d, o
 d = derived ();
 o = other ();

!!!!! test failed
mismatch in number of fields
shared variables   scalar structure containing the fields:
    d: 0x0 matrix
    o: 0x0 matrix


This is on OSX 10.9.1 with octave-3.8.0-rc2, can anyone confirm this behaviur?
Any idea what could be causing it?

c.
