Memory Crash with std::vector<std::string> on Mac OSX 10.6 #264

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I am trying to test functions from a class that use std::vector<std::string> as 
a return type. It crashes when I test in 
GoogleTest, but the code works fine if I use a separate program to run it.

I'm not sure if the issue is related to GCC 4.2 vs. GCC 4.0, since the issue in 
my test project disappears if I switch to 
GCC 4.0, however in my actual project I'm still seeing these memory issues with 
GCC 4.0

What steps will reproduce the problem?
1. Create a std::vector<std::string> or std::vector<int> in a class function
2. Test the function in a google Test with ASSERT_TRUE(true) at the end of the 
test
3. Run in 10.6 with GCC 4.2

What is the expected output? 

The tests should run without any memory cleanup. The objects that are created 
are on the stack. GoogleTest 
appears to be trying to clean them up.

What do you see instead?

With 10.6 and GCC 4.0 I don't get any errors, but with 4.2 I get the following 
on i386.

What version of Google Test are you using? On what operating system?

Building from source R. 395 on Mac OS X 10.6.2 using the Debug gtest framework.

I create a project with building for 10.6 with GCC 4.2 and it crashes 
withoutput:

Please provide any additional information below, such as a code snippet.

I've attached an Xcode test project that uses the gtest framework to test a 
simple class. If no ASSERT's are made it 
works fine, but when the ASSERTS are used to test the code it will cause a 
malloc error.

//  MyVector.h
#include <vector>
#include <string>

namespace abc {

    class MyVector {
    public:

            // Create a stack vector<string> and return a copy
        std::vector<std::string> getVector() const;

            // Create a stack vector<string>
        void makeVector();
    };
}

// MyVector.cpp
#include "MyVector.h"

namespace abc {

    std::vector<std::string> MyVector::getVector() const {
        std::vector<std::string> strVector;
        strVector.push_back("hello");
        strVector.push_back("goodbye");
        return strVector;
    }

    void MyVector::makeVector() {
        std::vector<std::string> strVector;
        strVector.push_back("hi");
        strVector.push_back("bye");
    }
}

// TestVector.cpp
#include <gtest/gtest.h>
#include "MyVector.h"

namespace abc {

        // Test the creation of a vector on the stack
    TEST(TestVector, MakeVector) {
        MyVector myVector;

        myVector.makeVector();

        ASSERT_TRUE(true);  // Crash
    }

        // Test the creation of a vector on the stack, return a copy
    TEST(TestVector, ReturnVector) {

        MyVector myVector;
        std::vector<std::string> v = myVector.getVector();

        std::vector<std::string>::iterator iter;
        for(iter = v.begin(); iter != v.end(); ++iter) {
            std::cout << *iter << std::endl;
        }

        //ASSERT_EQ(true, true);    // Crash 
        ASSERT_TRUE(true);  // Crash
    }

}

This seems issue 189.  It doesn't seem to be caused by gtest.
