I found a very strange surface visualization problem.
Please see attached IGES file.
Our environment: VC12 32bit. OCC 7.0.0 or 7.2.0
The problem occurred also on ImportExport application from MFCSamples.
The application has imported IGES file fine, but stuck into display function. I investigated the source code. The problem caused in the StdPrs_CurveDeflection file in the application enters into drawCurve function. Into drawCurve function app. goes into GCPnts_TangentialDeflection Algo(aCurve, theU1, theU2, anAngle, TheDeflection); and stuck there about 100 seconds, and Standard_OutOfMemory esception occured.
Under OCC 6.7.0 this IGES works well and fast.
Please help me to solve the problem or to find workaround.
Thanks in advance
