R crashes if print() is called on a previously deleted node

[tdeenes]

The call .Call(gdsNodeValid, x) in print.gdsn.class crashes the R session if x is a previously deleted node.

library(gdsmt)
f <- createfn.gds("test.gds")
n <- add.gdsn(f, "vec", 1:10)
delete.gdsn(n, TRUE)
## THIS WILL CRASH YOUR R SESSION!!!
# print(n)

Actually, your problem is as the same as the issue #3: print a non-existent GDS node, which was deleted or created by other (forked) process.

I will try to fix this problem before the next release of Bioconductor (Oct).
