Here is the code section that actually crashes:
for (unsigned i=0; i<frames; i++)
    {
     Matrix F(4,4); // functional alignment matrix
     double angle;
     F=BA.inverse() * Jtertiary.at(i) * MA; // tertiary axis functional alignment
     //Remove Tertiary Translation
     trans(x)=F(x,3);   trans(y)=F(y,3); trans(z)=F(z,3);
     trans(tertiaryaxis)=0;

     if (tertiaryaxis==X)
      {
       angle=ExtractX(F.inner(), RotationSequence);
       F=(Xrot(angle).transpose() * F.inner()).homogeneous();
       F(x,3)=0; F(y,3)=trans(y); F(z,3)=trans(z);
       F3.at(i)(1)=trans(x);   F3.at(i)(2)=trans(y); F3.at(i)(3)=trans(z);
     }
     else if (tertiaryaxis==Y)
      {
       angle=ExtractY(F.inner(), RotationSequence);
       F=(Yrot(angle).transpose() * F.inner()).homogeneous();
       F(x,3)=trans(x); F(y,3)=0; F(z,3)=trans(z);
       F3.at(i)(1)=trans(x);   F3.at(i)(2)=trans(y); F3.at(i)(3)=trans(z);
     }
     else if (tertiaryaxis==Z)
      {
       angle=ExtractY(F.inner(), RotationSequence);
       F=(Zrot(angle).transpose() * F.inner()).homogeneous();
       F(x,3)=trans(x); F(y,3)=trans(y); F(z,3)=0;
       F3.at(i)(1)=trans(x);   F3.at(i)(2)=trans(y); F3.at(i)(3)=trans(z);
     }
     else
        throw("ERROR: Tertiary Axis designation invalid for Three Axis Functional Alignment.\n");
     F3.at(i)(0)=degrees(angle);  //sets rotation about axis value into the final answer vector
     E.push_back(BA * F * MA.inverse()); // revised J matrix without tertiary rotation

     if (angle<minangle) minangle=angle;
     if (angle>maxangle) maxangle=angle;
    }


When it crashes it typically crashes at
E.push_back(BA * F * MA.inverse());


E is another vector of Matrix that was passed by reference to this function. My matrix class contains a number of functions that allows for matrix algebra.

I know I could probably re-write the Matrix class to use vectors, but I've been using it for over 10 years (written before I knew about vectors) and I figured if it ain't broke don't fix it. But maybe it is broke, and it just took this long for it to become a problem. If it is broken, can you tell me where?
