Instable case testing 3d offset algorithm (problem with cone-like surfaces)
Description
The case is
chl 937 A6
There are some BSpline surfaces that look like cones in initial shape, 3d offset fails. The problem is in usage of Geom_OsculatingSurface.

the inner initial surface "InitSurf" is now approximated if its degree is too low.

SVN branch http://svn/svn/occt/branches/22834 is ready for reviewing
Seems Ok to me, please rebase on trunk and test
Dear Commenter 2,
Workbench KAS:dev:apn-22834-occt was created from SVN branch http://svn/svn/occt/branches/22834
(and apn-22834-products from trunk) and compiled on Linux and Windows platforms.
There are compilation errors on Linux and Windows:
Error : Cyclic dependency detected between: Adaptor3d AdvApprox GeomAdaptor TColGeom Geom GeomConvert TKG3d GeomLProp TKGeomBase

Problem is reproduced till now
I cannot reproduce unstable behavior for Windows, debug mode.
According to info of MKV, bug chl 937 A6 is now tests/bugs/modalg_4/bug8842_6.
Please test it for different platforms and modes.
Use please pure master version, without any correction made by Author for this bug.
