[ESS] R-2.3.0 crash

[Stephen Eglen]

Thanks Robin; this seems odd.  Any other Mac users (David R?)
get the same thing?

I'm a little puzzled how it might be an ESS thing, maybe we are not
setting the environment correctly for R to start.  But was this a
problem with R-2.2.x series?

Another way forward  is to debug the R process, which may take work.  
e.g. you will need to follow the instructions in the R FAQ for
debugging R within ESS: (Sec 6.3 Debugging R from within Emacs)

----------------------------------------------------------------------
   If you have ESS, you can do `C-u M-x R <RET> - d <SPC> g d b <RET>'
to start an inferior R process with arguments `-d gdb'.

   A third option is to start an inferior R process via ESS (`M-x R')
and then start GUD (`M-x gdb') giving the R binary (using its full path
name) as the program to debug.  Use the program `ps' to find the
process number of the currently running R process then use the `attach'
command in gdb to attach it to that process.  One advantage of this
method is that you have separate `*R*' and `*gud-gdb*' windows.  Within
the `*R*' window you have all the ESS facilities, such as object-name
completion, that we know and love.
