Re: [ros-users] Illegal instruction

This produces a warning during compilation: "warning: cannot pass
objects of non-POD type ‘struct std::string’ through ‘...’; call will
abort at runtime". However, the warning itself was a little confusing
for me, and there's always a chance of compiling with warnings turned
off.
