Certainly, and here is a short history of this issue:
------------------------------------------------------------------------ 
------------------
I'm trying to install 1.2.1 onto an amd64 Gentoo system and "make  
check" comes up with this error:

Testing extraction of rotation angle from 3x3 matrices
ImathTest: testExtractEuler.cpp:229: void  
<unnamed>::testRandomAngles33(): Assertion `Imath::equal (angle,  
angleEx, eps)' failed.
FAIL: ImathTest
===================
1 of 1 tests failed
===================
------------------------------------------------------------------------ 
------------------
This first change added some extra output to aid debugging:

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;
------------------------------------------------------------------------ 
------------------
Line 217 in testExtractEuler.cpp
    float eps = 8.0 * limits<float>::epsilon();
------------------------------------------------------------------------ 
------------------
Line 100 in
    if (abs (D[j][k]) > 0.000002)
------------------------------------------------------------------------

Attached is the modified testExtractEuler.cpp.
