Re: [ecasound] ecasound interactive-mode segfaults on a '\' at the end of line

Hi Koen, I don't why know but I can't send emails to the list, could you
send it for me? Thanks

Hi,
I think that the problem is in vector<string>
kvu_string_to_tokens_quoted(const string& s) (kvu_utils.cpp). In the
loop checks if the character is "\\" and in this case makes p++ but at
the end of this iteration makes a new p++ so, if the character "\\" is
the last of the string, p never is equal to s.end() and doesn't exit the
loop. Here is my fixed code:
vector<string> kvu_string_to_tokens_quoted(const string& s)
{
  vector<string> vec;
  string stmp;
  bool quoteflag = false;

  for(string::const_iterator p = s.begin(); p != s.end(); p++) {
    if (*p == '\"') {
      quoteflag = !quoteflag;
    }
    else if (*p == '\\') {
      if ((p+1) != s.end()) {
        p++;
        stmp += *p;
      }
    }
    else if (isspace(*p) == 0 || quoteflag == true) {
      stmp += *p;
    }
    else {
      if (stmp == "") continue;
      vec.push_back(stmp);
      stmp = "";
    }
  }
  if (stmp.size() > 0)
    vec.push_back(stmp);

  return vec;
}

Pedro
