Hello,
I was trying this bit of code (i know it is an extreme case)

g=function(r){
? if(r==1)
? ? ? ?return(list(x=1))
? ?else
? ? ? ?return(list(x=g(r-1)))
? ?}

For z=g(500), the code runs but when I print z i.e
?>> z
I get
<environment: R_GlobalEnv>

?*** caught bus error ***
address 0x1, cause 'non-existent physical address'

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace

Running on Leopard, Macbook (intel, 4gb ram)
R version 2.9.2 (2009-08-24)
