Possible null pointer usage in memcpy() call.

After going through with clang tidy, there was at least a possible memory corruption error that was found.

language-master\src\elf64.c(521,9): warning GE6DAE51F: Null pointer argument in call to memory copy function [clang-analyzer-unix.cstring.NullArg]
        memcpy(t->buf + t->size, str, len + 1);

Might be a false positive, as everything else was pretty ok.
