Set is not inserting

I have a problem where my code just seems to get stuck when trying to insert into a set. 

using namespace std;
set<string> * lexset;


void build( const set<string>& word_list )
   set<string>::iterator it = word_list.begin();

   while( it != word_list.end()) 
   {
      cout << *it << "before"<< endl;
      lexset->insert(*it);
      cout << "after" <<endl;

      ++it;
      cout << "end of while" <<endl;
   }
}

It seems to get stuck before the line that prints out 'after'.

The line before insertion prints out a string and I know for sure that wordlist contains a lot of words. This compiles and doesn't loop. If I remove the insert, it iterates through just fine. Why is this insert causing so much trouble?

Allocate memory first for lexset :

lexset = new set<string>;

And fix your word_list typo
