Gcc Option -O2 is used for compiling.
I start Geany, open a file and use "Tools->Split Window->Vertically" (or Horizontally) and sometimes it crashes then. Below a stack trace of such an event ...

It might be a 32/64 bits problem. See splitwindow.c[167]:

The usage of GPOINTER_TO_INT() looks strange to me. So I'll apply the patch below and test ...

Thanks for reporting and for the patch (will be committed it later).
Just for your interest, I used the type "sptr_t" which is defined in Scintilla and typically used for the fourth argument of scintilla_send_message(). But it's simply a typedef for the long type, so it does the same as your patch.
