Memory Error with std:ostringstream and -std=c++11? [duplicate]

Answer 1

Take a closer look at this line: const char* stmt = qs.str().c_str();

qs.str() provides you a temporary std::string object from which you take a pointer to inner char* array. Once this line completes its execution, your pointer is no longer valid and something else may (and probably is) stored there.

Try doing this instead:

std::string strstmt(qs.str());
const char* stmt = strstmt.c_str();
