The following gives an immediate segmentation fault, v 0.90.1
"fred" <- function(x) { print(x); Recall(x-1)}
fred(0) # segmentation fault at recursion 831
Obviously this recursion is non-terminating, but shouldn't it be caught
and reported at some limit? In 0.64.1 we had
Error: protect(): stack overflow
at recursion 831. Cheers, Jonathan.

The development version has ... [1] -162 [1] -163 Error in print(x) : evaluation is nested too deeply: infinite recursion? The limit can be set with options(expressions=...)
