However, the code that implements 'lapply', function 'do_lapply' in apply.c,
seems to support long vectors.
The error message points to memory.c:1652. I don't understand the code there.
A different case:
gc()
after
system.time(vector("list", 2^31))
gave an error with message pointing to memory.c at different line. Subsequent
gc()
didn't give error.
system.time(vector("list", 2^31))
