c - addr2line - 在基本示例上失败

Question

#include <stdio.h>

void __cyg_profile_func_enter(void *func, void *caller) __attribute__((no_instrument_function));
void __cyg_profile_func_exit(void *this_fn, void *call_site) __attribute__((no_instrument_function));

void __cyg_profile_func_enter(void *func, void *caller)
{
    printf("%p\n", func);
    printf("%p\n", caller);
}

void __cyg_profile_func_exit(void *this_fn, void *call_site)
{
}

void my_function(int a, int b)
{
    a = a * b;
}

void dummy_function()
{
    int a = 10;
    int b = 20;
    my_function(a, b);
}

int main()
{
    int x = 42;
    int y = 73;
    dummy_function();
    my_function(x, y);

    return 0;
}

构建命令:

gcc -x c boost_stacktrace.cpp -finstrument-functions -rdynamic -g -O0 -o boost_stacktrace.exe
./boost_stacktrace.exe | tee addrs.txt

将 -no-pie 添加到编译命令后，它起作用了。
