Cette question est la suite de ma question .
Voici le code qui pose problème.
a.h :
#include <string>
#include <vector>
std::vector<std::string> foo();
a.cpp
#include "a.h"
std::vector<std::string> foo()
{
std::vector<std::string> v;
return v;
}
et enfin main.cpp :
#include "a.h"
#include <iostream>
int main()
{
std::vector<std::string> s = foo();
return 0;
}
Compilation comme suit (main.cpp est compilé avec le drapeau de débogage STL) :
g++ -c a.cpp
g++ -D_GLIBCXX_DEBUG main.cpp a.o
Lors de l'exécution de a.out, le processus se bloque :
Core was generated by `./a.out'.
Program terminated with signal 11, Segmentation fault.
