Compiling with -Wall causes stringop-truncation error

[viking]

After running ./configure and make, here's what happened:

cc -MD -Wall -O2 -g -std=c99 -D_GNU_SOURCE -pipe -DTHREAD_SAFE -Werror   -DLIB_DIR=\"/usr/local/lib\" -DINSTALL_PREFIX=\"/usr/local\" -DDLL_NAME=\"libproxychains4.so\" -DSYSCONFDIR=\"/usr/local/etc\"  -fPIC -c -o src/core.o src/core.c

modify src/core.c

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wstringop-truncation"
strncpy(data->addr_name, name, sizeof(data->addr_name));
#pragma GCC diagnostic pop

same for strncpy(space->addr_name, node, sizeof(space->addr_name));
