Details:

The BIST test.m function in Octave incorrectly reports the value of shared
variables as they were before a failing test was executed, rather than their
actual value during the test that failed which could be germane.

Sample code attached as tst_report.m.  Run "test tst_report.m" and observe
that the value for variable B is the initialized value from the start of the
file rather than the value that it actually holds during the %!test.

File tst_report.m:


%!shared A, B
%! B = magic (5);

%!test
%! B = diag ([1 2 3]);
%! assert (0);
%! #assert (1);

%!test
%! assert (0);


For further confirmation, comment out "assert (0);" in the first test and
uncomment "assert (1);".  The second test will now execute and it will show
the correctly modified value of B.
