does this file cause a leak?
does this file cause a leak?
hi
i'm getting an mfc memory leak dump when i use a particular dxf file with our application. i've reproduced the problem by wrapping odreadex in an mfc stub. to test, unzip the archive into dd_nonlibs\examples of dwgdirect 2.04.01 and run in debug mode.
i've also included a file that doesn't cause a memory leak dump. change the project command arguments from leak.dxf to noleak.dxf to confirm.
thanks

thank you for the project to reproduce the situation.
the leak is caused by odreadex dumping code for polyface mesh. the fix is (exprotocolextension.cpp):
code:
/************************************************************************/
/* polyfacemesh dumper */
/************************************************************************/
class oddbpolyfacemesh_dumper : public oddbentity_dumper
{
public:
void dump(oddbentity* pent, int indent) const
{
....
for (; !piter->done(); piter->step())
{
// oddbpolyfacemeshvertexptr pvertex = piter->entity()->queryx(oddbpolyfacemeshvertex::desc());
oddbpolyfacemeshvertexptr pvertex = oddbpolyfacemeshvertex::cast(piter->entity());
if (!pvertex.isnull())
{
....
}
else
{
// oddbfacerecordptr pface = piter->entity()->queryx(oddbfacerecord::desc());
oddbfacerecordptr pface = oddbfacerecord::cast(piter->entity());
if (!pface.isnull())
{
