The following commands causes R to crash:
a = array(1:3)
dimnames(a)[] = c('1','2','3')
not naming the array seems to work.

Thank you for the good bug report.
A shorter version is
cor(as.array(c(a=1, b=2)), cbind(1:2))
The internals assume to have either a matrix or a vector when
the other argument is a matrix.
I'm still thinking about where to fix the bug, in C or in R.
What I find is that R also excepts list()s as arguments to
cor(), cov(), etc. which I think should rather give an error,
Fixed in 1.9.1 patched
