Dear Dr. Ripley,

Believe it or not, there are several people on this list who are not
Dr.Ripley. In fact, I suspect that he is temporarily absent these
days. Had he been present he would likely have explained that none of
us need to read the same message five times over...

I'm using the R v1.11 on Macintoch and I seem to have a problem with the

Say what? There was never an R version with that number. Is this Mac OS X
or classic Mac?

function R_alloc. It crashes when using the following .C function (only an
example):

*How* does it "crash"? R shuts down? Prints an infinite stream of "salut!!!"?
What did you do to compile and did you see any warnings from the compilation?

///////////////////////////////
# include <R.h>
void Hello(int *n)
{
int i,x;
for(i=1;1< *n ; i++)
{
	Rprintf('salut!!!\n');
}
x = (int *) R_alloc(5,sizeof(int));
}

///////////////////////////////

I call it in R with this line:

.C('Hello',as.integer(5))

and then what happens?

Any idea why and how I can resolve this problem?

Well, if that is really your code, x is an int that gets an int *
assigned to it, but 1 is never going to be bigger than *n, so I don't
see how you'd get that far.
