Random syntax error

[jamesjuett]

Repro below. This shouldn't be a syntax error.

#include <iostream>
#include <string>
using namespace std;

void replace_char(char *str, char to_replace, const char *replacements) {
    // create these two to keep track of which character we are on in both strings
    int strCounter = 0; 
    int replacementsCounter = 0; 
    while(true) {   
      // if we reach the end of the string then break out of the loop
      if(*(str + strCounter) == '\0') break;  
      // if it finds the current character matches the char to replace
      else if(*(str + strCounter) == to_replace) {  
                // replaces the character in the string
                str + strCounter = *(replacements + replacementsCounter);   
                if(*(replacements + replacementsCounter) == '\0') {  
              // we are out of replacement characters
                break; 
            } 
                else {  
              // we used a replacement character so move onto the next one
              replacementsCounter++;  
            }
      }   
      // move onto the next character in the string
      strCounter++; 
    } 

}

int main() {
  char str1[6] = "hello";
  replace_char(str1, 'h', "jeans");
  string str1_string("jello");
  assert(str1 == str1_string);

  char str2[7] = "giggle";
  replace_char(str2, 'g', "ab");
  string str2_string("aibgle");
  assert(str2 == str2_string);

  char str3[5] = "eecs";
  replace_char(str3, 'e', "pine");
  string str3_string("pics");
  assert(str3 == str3_string);

  char str4[12] = "x-x-x-x-x-x";
