Summary: Drag and drop panels crashes on OSX Lion 64 bits
Initial Comment:
When dragging and drop a panel (even to its previous dock book) it crashes.
Debug info shows a bad memory access:
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: 13 at address: 0x0000000000000000
0x0000000100155886 in studio::DockBook::on_drag_data_received
(this=0x1053be8f0, context=@0x7fff5fbfebe0, unnamed_arg=0, unnamed_arg=0,
selection_data=@0x7fff5fbfebd8, unnamed_arg=0,
time=1597954092) at dockbook.cpp:94
94 if(dockable.parent_)

Message:
To fix this bug it is needed to properly pass the pointer data of the
dragged panel to the SelectionData class. Currently it assumes that the
size of a pointer to DockBook ** is 4 bytes, which seems to be wrong for
some architectures.
I changed the hardcoded '4' by sizeof(DockBook **) what is the data stored
in the SelectionData class.
