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 (I
don't know if this is reproducible on other configs since this is the
only computer with enough memory I have access to...)
You will find below a simple somewhat reproducible (usually it
crashes around 5.5GB of vsize, sometimes it gets into an infinite
loop) exemple and the relevant sessionInfo.
Is this a "normal" limitation of R, a problem with my config or a
*cough* bug ?
best regards,
Simon.
