My first bug report, please let me know if I am missing anything.
Running...
$ cat minimal.cpp && echo "-----" && g++ -Wall minimal.cpp && a.out
Produces...
#include <iostream>
#include <map>
#include <string>
using namespace std;
int main() {
map<const char*, int> hash;
string sElement;
sElement = "ab1";
cout << sElement.c_str() << (( hash.find(sElement.c_str()) != hash.end() )
? "\t\tfound\n"
: "\t\tnot found\n");
sElement = "ab2";
cout << sElement.c_str() << (( hash.find(sElement.c_str()) != hash.end() )
? "\t\tfound\n"
: "\t\tnot found\n");
// string aux = sElement;
if( hash.find(sElement.c_str()) == hash.end() )
hash[sElement.c_str()] = 7;
sElement = "ab3";
cout << sElement.c_str() << (( hash.find(sElement.c_str()) != hash.end() )
? "\t\tfound\n"
: "\t\tnot found\n");
return 0;
}
-----
ab1 not found
ab2 not found
ab3 found
There, the last line should be "ab3 not found", which can be
obtained by removing "//" from the only commented line.
