segfault when applying strange coercion (PR#2923)

I made a mistake -- and R crashed. A (more or less) reproducible example seems to be: x <- matrix(nrow=20000, ncol=20) x$any <- numeric(0) It is possible to crash R by executing these lines several times (1 - 20) on Windows as well as on Solaris (might be related to PR#2880 - let's call it "non-existing list elements")
Linux too: (r-devel) ...
x <- matrix(nrow=20000, ncol=20) ; x$any <- numeric(0)
Warning message: Coercing LHS to a list
x <- matrix(nrow=20000, ncol=20) ; x$any <- numeric(0)
