The bug in foreign function calling pointed out by Martin in a different
context does this, if you haven't fixed it (it's more recent than 50a3).
In naoktrim in dotcode.c, which begins
static SEXP naoktrim(SEXP s, int * len, int *naok, int *dup)
{
SEXP value;
if(s == R_NilValue) {
value = R_NilValue;
*naok = 0;
*dup = 0;
*len = 0;
}
change *dup = 0 to *dup = 1.
