Works for me:

address@hidden pr12772]$ cat x.cc
#include <string.h>
#include <stdlib.h>
#include <unistd.h>

extern "C" int __attribute__((visibility("default"))) func(char *ptr)
{
    static const char g_const[] = { 1, 1, 0 };
    memcpy(ptr, g_const, 3);

    return 0;
}

extern "C" char *func2(char *ptr)
{
    static char buf[4096];
    if (!getcwd(buf, sizeof(buf)))
        buf[0] = 0;
#define STR "test_string"
    memcpy(ptr, STR, sizeof(STR));
    return buf;
}
address@hidden pr12772]$ make
g++  -c -fpic -O3 -fdata-sections -ffunction-sections
-fvisibility-inlines-hidden -fvisibility=hidden -o x.o x.cc
g++  -shared -Wl,-gc-sections -o x.so x.o
readelf -r x.so
