Hi all,
In my c++ application (Linux Fedora Core2) i am using the STL string , for memory leak check i used the valgrind , i set the environment variable as follows export GLIBCPP_FORCE_NEW=1 (or) GLIBCXX_FORCE_NEW=1 , the valgrind report showing memory leak in the STL string, Please tell me whether STL string have memory leak or not ?


Part of Valgrind leak summery:

Part of My code:
-----------------
valgrind showing leak in the following line:

id = "<" + responseId + ">";

NodeWatch::NodeWatch(Watch *watchInstance,string responseId, Threshold **thresholdArray, string pollinterval)
{
string id;
watch = watchInstance;
id = "<" + responseId + ">"; // Valgrind showing leak in this line
thresholds = thresholdArray;
pollInterval = atoi(pollinterval.c_str()) / 10;
}


Thanks,
