HiIn my R package, imagine I have a C function defined: void myfunc(int *x) { // some code } but when I call it, I pass it a pointer to a longint instead of a pointer to an int. Could this practice potentially result in a segfault?
I don't think the passing would cause a segfault, but "some code" might be expecting a positive number, and due to the type error you could pass in a positive longint and have it interpreted as a negative int.
