Modeling Algorithms - Sweep with acute angle in spine produces wrong intersection results [24991]

[dpasukhi]

Description

When sweeping along paths with acute angles (<90deg) the resulting shape is not a valid solid. The faces get extended but the intersection is not performed.
A debug build gave the following output:
Compile with option DEB : if problems with intersection : IntWalk_PWalking_1.gxx (lbr le 1erdec98)
The when using Round corner transition the result is also wrong but does not give this message.
