I can be a bit more precise - I have both 32-bit R and 64-bit R built
and installed on fedora 8 64-bit, just one and same box.
32-bit R finishes quite quickly with:
> proc.time()
user system elapsed
0.772 0.032 10.147
64-bit R takes up 49s CPU time (from ps). This is long compared to
either 10s (elapse) or 1s (user+sys). And it ends with:
Error: protect(): protection stack overflow
So yes, it looks like a 64-bit R specific bug.
