Hi,
There are 2 dangers with using 'DUP=FALSE' mentioned:
* formal arguments
* lists
Would you also mention a third one, namely

Mathieu,
I do not understand what you mean in your email.
I am only interested in the cause of the valgrind
message in
> .Call("XXX")
[1] 1
> nd <- 3
> solve(diag(nd) , as.vector(1:nd))
[1] 1 2 3
> .Call("XXX")
==25734== Conditional jump or move depends on uninitialised value(s)

I would be happy to get any hint that explains this behaviour.
The LeakSanitizer message appears in the interactive mode,
but not in the batch mode.
With kind regards,
Martin Schlather
