c4e1d8c918 0032915: Geom2dAPI_InterCurveCurve, The algorithm lost an intersection point.
Get rid of strange code: preliminary check of self-intersections is made on a polygonal representation of a curve, it is able to find possible intersections, but after that it filter out segments neighbor to the pair of non-intersected segments.

Test case de step_4 I1 has been marked BAD, because the self-intersection is treated correctly, but the projection algorithm generates such crooked 2D curve.

Reference data in test cases heal split_angle_advanced ZA5 and ZA6 has been updated, because those shapes have self-intersected edges, which are being detected now.

b776f4ee07 0032929: Modeling Algorithms - Crash in PerformIntersectionAtEnd after deletion of surfdata
When creating a fillet, num is calculated via ChFi3d_IndexOfSurfData. If it
returns just the number of entries in surfdata, it can happen that this
value becomes invalid when handling the case "two faces common to the edge
are found". When both components are on an arc, there will be num removed
from the surfdata.

num would then be larger than the number of entries surfdata. The derived
num1 is therefore also incorrect. The subsequent usage of this
value will either:

* Debug build: cause an out of bounds exception in ChangeValue
  (`SeqFil.ChangeValue(num)`)
* Release build: cause a segfault when retrieving it via index num1
  (`SeqFil(num1)`)

num + num1 must be recalculated after the deletion happens to correctly
calculate the fillet.

90e61140aa 0032930: Modeling Algorithms - Crash in PerformIntersectionAtEnd when no face was found
The PerformIntersectionAtEnd code is currently not handling all the faces
correctly. If it retrieves Face[0] as F, it can happen that the previously
ran code didn't actually retrieve any faces in this array at all.

For example when:

* "if (nface==3)" is true
  - "if (!findonf1)" is true (doesn't assign any faces to this array)
  - "if (!findonf2)" is true (doesn't assign any faces to this array)
  - "if (state == ChFiDS_OnSame)" is not true (because it is
    ChFiDS_AllSame)
  - "if (findonf1 && !isOnSame1)" cannot be true (see above, but would
    handle faces)
  - "if (findonf2 && !isOnSame2)" cannot be true (see above, but would
    handle faces)
  - "if (isOnSame2)" is false (but would also handle faces)

Since no faces were assigned here, F would be a NULL face. As result, the
function will crash when trying to access the Surface behind the face via
`BRep_Tool::Surface(F);`.

While the best approach would be to identify the implementation bug in the
algorithm behind PerformIntersectionAtEnd, a check + exception is used
instead because the actual algorithm is not known.

19a49b8e74 0032931: Modeling Algorithms - Crash in ChFi3d_IsInFront when no face was found
The ChFi3d_IsInFront code is currently not handling all the combinations
correctly. For example, if `if(fd1->IndexOfS2() == fd2->IndexOfS2())` is
true, it can happen that the `TopoDS::Face(DStr.Shape(fd1->Index(jf1)))`
returns a Face with entity == NULL. The subsequent usage of this NULL face
in `BRep_Tool::Parameters( Vtx, face )` will then cause a segfault.

While the best approach would be to identify the implementation bug in the
algorithm behind PChFi3d_IsInFron, a check + exception is used instead
because the actual algorithm is not known.
