I meant the method windowWillCloseNotifications in RDocumentController.m
1. change “QuartzCocoaView” to something otherwise to avoid it being invoked,
2. compile the R GUI
3. run the plot function, e.g. plot(1,1)
4. close the quartz
you will see the error EXC_HAD_ACCESS (code=EXC_i386_GPFLT).
there may be a memory leak in R code!?
