[Rd] R process killed when allocating too large matrix (Mac OS X)

Dear expeRts,

The following code leads to R being killed (under Mac OS X 10.11.4; R
installed from source; also happened under a previous unstable

m <- matrix(0, 100000, 100000)

I expected an error that a vector of this size could not be allocated.

Besides the above (a bug?), how can I find out beforehand whether or
not a square matrix can be allocated?
