Is the domain name above really valid?

In this case, I think you need to use what we call a "cleanup",
because execute_command might trigger an "error" (GDB's poor man's
exception mechanism), thus prevening the last xfree from releasing
buf.

A formatting nit: The GNU Coding Standard, which we follow in GDB,
requires a space before opening parens.

While looking at this code, I don't think you'll need 2 xstrprintf
either. Can you try the attached patch?
