[R-SIG-Mac] segmentation fault

[Simon de Bernard]

Dear list,

I am having a segfault while working with large lists in R 2.4.1  
patched (64-bit compilation) on an apple xserve xeon with 16GB RAM

You will find below a simple somewhat reproducible (usually it  
crashes around 5.5GB of vsize, sometimes it gets into an infinite  
loop at that memory usage) exemple and the relevant sessionInfo.

I have sent a mail to R-devel and Luke Tierney was not able to  
reproduce the problem with a 16GB x86_64 linux machine so I'm now  
trying R-SIG-MAC...

Any idea?

best regards,

Simon.
