Re: [Quickfix-developers] NewOrderList addgroup threw "Attempted to read or write protected memory. This is often an indication that other memory is corrupt"

[Djalma R. d. S. F. <drs...@gm...>]

This error occurs because the .NET runtime sometimes moves the objects in
memory to compact the GC Heap, this cheats the unmanaged code and leads to
an access violation. The solution is pinning the objects involved.

void addGroup( Group* group )
  { QF_STACK_TRY
    if ( !group ) { throw new System::ArgumentNullException(); }
    Group __pin *pThis = this;
    Group __pin *pGroup = group;
    pThis->unmanaged().addGroup( pGroup->unmanaged() );
    QF_STACK_CATCH
  }
