Re: [Openexr-devel] ImathTest Failure

[Florian Kainz]

Hi Dan,

Would you mind trying the following:

In file testExtractEuler.cpp, just before line 229, which reads

    assert (Imath::equal (angle, angleEx, eps));

insert these print statements:

    cout << setprecision (10);
    cout << M << endl;
    cout << "angle " << angle << endl;
    cout << "angleEx " << angleEx << endl;
    cout << "eps " << eps << endl;

then re-run the confidence test.  You should get a lot of output
that looks like this:

    angle 2.275887251
    angleEx 2.275887251
    eps 5.960464478e-07
    (  6.6362828016e-01  -7.4806249142e-01   0.0000000000e+00
       7.4806249142e-01   6.6362828016e-01   0.0000000000e+00
       0.0000000000e+00   0.0000000000e+00   1.0000000000e+00)

    angle -0.8451377153
    angleEx -0.8451377153
    eps 5.960464478e-07
    (  8.5939532518e-01  -5.1131170988e-01   0.0000000000e+00
       5.1131170988e-01   8.5939532518e-01   0.0000000000e+00
       0.0000000000e+00   0.0000000000e+00   1.0000000000e+00)

Please send me the last 20 lines of the output before the assertion
failure.

Also, can you make the error go away by changing the optimization
level (-O0, -O1, -O2)?
