R Freezes while Document editing

If it helps, a colleague of mine and I also get the freezing + segfaults a 
few times a day. They also occur while typing into the code editor in 
R.app 
[both of us are using R version 3.1.2 (2014-10-31); Platform: 
x86_64-apple-darwin13.4.0 (64-bit) ]. 

They seem to be more frequent while trying to use command+z (undo) several 
times in a row. Maybe some thread is scanning/parsing the file after each 
change and it can't keep up with rapid undo?

Ah - sorry if this was unclear: 
I don't know if the warning is related to the segfault. I just started 
noticing both at about the same time. 
When the segfault occurs, R is frozen. The console displays an options 
dialogue for shutting it down, but accepts no input. 

With several more freezes today a pattern seems to emerge: once I have 
edited for a while, the freeze happens when I select a part of a line of 
code.

For a couple of days I have been seeing a (system generated) warning 

after I open a document, when I change focus into that document: 

2014-12-04 15:05:21.336 R[73463:707] *** 
WARNING: Method convertPointFromBase: in class NSView is deprecated 

on 

10.7 

and later. It should not be used in new applications. 

This occurs also if the document is empty, however not with a 

document 

that has been freshly created in a new session. 

As well, I have experienced freezes (application not responding) 

right 

after R displays the segfault message, while 

editing the script file. The freezes are intermittent, after about an 

hour of coding or so - I can't reproduce them 

yet. 

Updating to 3.1.2 has solved neither of the problems. 

Is this a known problem? Is there anything I can contribute to get it 

solved? 

Thanks!

It's a warning. A programming paradigm used in older versions of OS X 

fell from favor in version 10.7. We still maintain a Snow Leopard (i.e. 

OS 

X 10.6) build. The question is whether the intended paradigm replacement 
actually works in 10.6; otherwise, it could be undesirable to maintain 

two 

different codes for the two different builds. 

I don't see the warning as related to any segfault? Being able to 

continue work following a segfault would be quite unusual so I suspect 

that 

you're using the term incorrectly. 

If you want to contribute, you might dig into the source code for 

R.app 

and figure out what it is that needs to be replaced and by what. And 

then 

whether the "what" is present in the Snow Leopard toolchain. The closest 

I 

can get is stuff like this:

Mind you, Simon might already know all about this and just needs to 

get 

around to sorting things out.
