Summary

0007287: Problem of Memory Leak

Description

This problem was reported by Marcel Keller - see forum thread
http://www.opencascade.org/org/forum/thread_7199/ [^]

Marcel Keller :
We recieved indications of memory leak problems from one of our customers and
simplified the code as shown below. After the for-loop memory increased about 30MB.

#include "TopoDS_Shape.hxx"
#include "TopoDS_Solid.hxx"
#include "BRepPrimAPI_MakeBox.hxx"
#include "BRepAlgoAPI_Cut.hxx"

int main(int argc, char* argv[])
{
TopoDS_Solid box1;
TopoDS_Solid box2;
for (int i=0; i<1000; i++){
box1 = BRepPrimAPI_MakeBox(100,100,100);
box2 = BRepPrimAPI_MakeBox(50,50,50);
BRepAlgoAPI_Cut cutOperation(box1, box2);
}
return 0;
}

Additional information
and documentation updates

Documentation remark, added by Oleg FEDYAEV (ofv) 2004-12-06 14:18:09:

Some memory leaks actual for boolean operations in memory management mode
MMGT_OPT = 0 are fixed.
