Hi!

sscanf returns 0 for the following code using musl, but glibc returns 1.
%15s cannot be used here since it stops on whitespace, but it's required to
get all remaining data after getting other fields with sscanf (not included
in this example).

#include <stdio.h>
#include <string.h>

int main(void) {
  char data[16];
  memset(data, '\0', sizeof(data));
  int res = sscanf("abcde", "%15c", data);
  printf("parse: %d %s\n", res, data);
  return 0;
}
