For reference, running your code in a build of R-devel with sanitizers:
> x <- vector(mode="list", length=3e9)
memory.c:2747:27: runtime error: signed integer overflow: 2147483647 + 1
cannot be represented in type 'R_len_t' (aka 'int')
SUMMARY: AddressSanitizer: undefined-behavior
Hi,
After I create a long list e.g. with
x <- vector(mode="list", length=3e9)
many bad things start to happen e.g. some things stop working with a
spurious error message:
gc()
# Error in gc() :
# long vectors not supported yet:
/home/hpages/src/R-3.3.2/src/main/memory.c:1137
