"Must be the same types" strange case

[alexander-penev]

This function is differentiate without problems:

float sphere_implicit_func(float x, float y, float z, float px, float py, float pz, float r) {
  return (x-px)*(x-px) + (y-py)*(y-py) + (z-pz)*(z-pz) - r*r;
}

but this

float sphere_distance_func(float x, float y, float z, float px, float py, float pz, float r) {
  return (x-px)*(x-px) + (y-py)*(y-py) + (z-pz)*(z-pz) - r;
}

generate compile time assertion:

Assertion failed: (lhs_derived->getType() == rhs_derived->getType() && "Must be the same types."), function VisitBinaryOperator, file /Users/alexanderpenev/clad/src/tools/clad/lib/Differentiator/DerivativeBuilder.cpp, line 453.

This workaround

float sphere_distance_func(float x, float y, float z, float px, float py, float pz, float r) {
  return (x-px)*(x-px) + (y-py)*(y-py) + (z-pz)*(z-pz) - r*1.0f;
}

also is OK.

Thanks for the report. Should be fixed in f915dd3.
