Thanks for the report - problem detected (due to a bogus 
function in htslib.c, line 2676) and fixed for the next 
release!

char* strrchr_limit(char* s, char c, char* limit) {
  if (limit == NULL) {
    char* p = strchr(s, c);
    return p?(p+1):NULL;
  } else {
    char *a=NULL, *p;
    for(;;) {
      p=strchr((a)?a:s, c);
      if ((p >= limit) || (p == NULL))
        return a;
      a=p+1;
    }
  }
}
