STL vector crash on Android x86_64

[hejia...@gmail.com]

The following code will crash at vector desconcrutor if I build the code for Android x86_64 with ndk-build(x86 worked well).

hello.cpp

#include <vector>
#include <stdio.h>

using namespace std;

int main(int argc, char* argv[])
{
    vector<int> vec;

    vec.push_back(11);
    vec.clear();

    vector<int> vec2(vec.size());

    return 0;    
}

Android.mk

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := hello
LOCAL_SRC_FILES := hello.cpp

include $(BUILD_EXECUTABLE)

Application.mk

APP_ABI := x86_64

APP_STL := stlport_static

It is weird. The value of vec.size() equals to 0. If I change the code as follows:

vector<int> vec2(0);

the app will not crash. The issue seems to be caused by compiler optimization. CFLAG -O2 is used by default. If I add another CFLAG, such as -O0 after it, the app will not crash either.

Does anybody know why?

Thanks!

You're using r10e, which has a much older and much worse version of both compilers. You should update to r12.

I tested r12, the same error.

Hmm. Could you file a bug at github.com/android-ndk/ndk/issues?

I encounter the same problem, I think there must be a bug in std::vector implementation.

I try to push 10 elements to vector, it crashed at 4rd element.  The element is a template class to hold some data, like auto_ptr in boost.

The same algorithm works in windows and iOS.

Then I use std::map to do it, using size of map as key, no more crash.
