[R] R 2.10 'memory leak'? on OS X

[Stropharia]

Dear R users,

I am running R 2.10.0 on OS X 10.5.8.

I had been running 2.10 successfully for about a week (and have used
previous R versions for 2+ years on the same computer) until 2 days ago it
failed to start up for me. Now when I try to start R, the application tries
to initiate for several minutes then crashes. Looking at the activity
monitor, my memory usage goes from having about 1.6Gb free (out of 2Gb) to
<7Mb in the first 10-15 seconds of attempting to start the program. At this
point I either have to force quit R (as everything starts to freeze up) or
wait several minutes for it to crash.

I have erased the application and reinstalled it 4 times now - with exactly
the same result. I looked around in the Library and System folders to see if
any other files needed to be removed, but couldn't find any. I have also
restarted the computer and repaired permissions multiple times - and then
reinstalled R, with no luck. The exact same thing happens if I start R64.

I did not updated OS X or R, or install any other programs, just prior to
this first happening and am at a loss to explain what's going on. I have
copied the first part of one of the crash logs below. Does anyone have any
ideas for to remedy this?

best,

Steve
