D21x RTOS SDK 1.0.5使能AWTK并添加C++源码后系统运行异常
经测试AWTK和C++源码只要不是同时使能，系统都能正常运行。但两都同时使能编译在一起运行就会进入不了main函数并出现Exception如下：

Re: D21x RTOS SDK 1.0.5使能AWTK并添加C++源码后系统运行异常
会不会是栈越界，C++代码加少一点试试

Re: D21x RTOS SDK 1.0.5使能AWTK并添加C++源码后系统运行异常
试过将main线程栈开到4MB都一样。C++代码如下，非常简单，且只是加入编译没有在其它地方调用C++源码的函数。
发现只要用了C++的标准库就出问题，不用C++标准库就没有问题；即使能宏ENABLE_CPP_STD就会出问题
#include <stdio.h>
#define ENABLE_CPP_STD 1
#if ENABLE_CPP_STD
#include <vector>
#endif
class MyOutputStream {
public:
MyOutputStream(){}
MyOutputStream& operator<<(int v) {
printf("%d", v);
return *this;
}
MyOutputStream& operator<<(unsigned int v) {
printf("%u", v);
return *this;
}
MyOutputStream& operator<<(long int v) {
printf("%ld", v);
return *this;
}
MyOutputStream& operator<<(unsigned long int v) {
printf("%lu", v);
return *this;
}
MyOutputStream& operator<<(char v) {
printf("%c", v);
return *this;
}
MyOutputStream& operator<<(const char* v) {
printf("%s", v);
return *this;
}
MyOutputStream& operator<<(char* v) {
printf("%s", v);
return *this;
}
};
class A {
public:
A();
~A();
private:
#if ENABLE_CPP_STD
std::vector<int> vi;
#endif
MyOutputStream cout;
};
A::A()
{
cout << "A init\n";
#if ENABLE_CPP_STD
vi = {1, 2, 3};
vi.push_back(4);
vi.push_back(5);
cout << "is size:" << vi.size() << '\n';
for(auto &i: vi) {
cout << i << ", ";
}
cout << '\n';
#endif
}
A::~A()
{
cout << "A deinit\n";
}
void a_test()
{
A a;

Re: D21x RTOS SDK 1.0.5使能AWTK并添加C++源码后系统运行异常
找到问题了！D21x是64位机，C++的初始化函数表.init_array应该是8字节对齐的，而SDK的链接脚本里弄成4字节对齐了。
按以下patch将链接脚本里的改为8字节对齐即可：
