splitting strings memory glibc kinda problem

[_sluimers_]

vector<char*> * Program::StringSplit(char * str, char * delim){
vector<char*> * results = new vector<char*>;
char * word;
word = strtok (str,delim);
results->push_back(word);

while (word != NULL){
word = strtok (NULL, delim);
if(word != NULL){
results->push_back(word);
}
}
return results;
}

It works with a string of one word and sometimes two.
Using more words and one of the words are no longer accurate.

But when using 7 words this is the first line of the very long error I get:
*** glibc detected *** ./shell: free(): invalid next size (normal): 0x08264300 ***

I'm not that good at programmnig. All I know is that is has memory problems.
What is wrong with this code and how should it be fixed in order to correctly split
strings?

That code is wrong.. it will not work..

Use std::string instead of char arrays and put a std::string object in the vector and not a pointer...

So the vector would have a declaration like this:

std::vector<std::string> vec_;
Also, pass that vector as an argument by reference to that function. Dont do dynamic allocation - to just make the vector live outside that function. It also asks for the caller to clean-up the dynamic allocations. Very bad practice.
