Hi!
Error is in svx/source/sdr/overlay/overlaymanagerbuffered.cxx
386: Window& rWindow = static_cast< Window& >(rmOutputDevice);
387: Cursor* pCursor = rWindow.GetCursor();
Maybe something is with the timing of instructions because there are two lines
which are exactly the same, and there works everything:
240: Window& rWindow = static_cast< Window& >(rmOutputDevice);
241: Cursor* pCursor = rWindow.GetCursor();
So defining rWindow in a wider scope (outside of if(bTargetIsWindow){...} line
238) - and using that same rWindow in subsequent occurrences - seems to solve
the problem, at least it makes it less frequent.
PS.: rWindow is of type Window, which has a member named mpWindowImpl. This is
not present in OutputDevice class which is the base class of Window. What value
will be assigned to mpWindowImpl in rWindow after Window& rWindow =
static_cast< Window& >(rmOutputDevice);
