[R-SIG-Mac] 64-bit build of R crashes while idle

[Simon Urbanek]

Steve,

thanks for the report. At a first glance from the crash log it seems  
possibly like a problem in the OS and not R itself. Note that 64-bit  
Cocoa applications are still rare on Leopard, so I'm not sure how  
stable GUI applications are in 64-bit. As Brian pointed out R itself  
is solid in 64-bit, so if you have issues, you can always run 64-bit R  
on the command line (Terminal).

Nonetheless any feedback on 64-bit R.app is highly appreciated since  
not many users appear to use it. Clearly, the more feedback we get the  
better we can make it.

Custom compilation is not really necessary. If there are any issues  
with our build then it is likely to be present in all builds.
