Please don't use sprintf(); it's an evil function since it doesn't
check for buffer overflows.  And even when you can prove that the
buffer is large enough, it's better not to use it, to make auditing
the code easier.  So please use xsnprintf() (or snprintf() outside of
GDB).

Or if you want to address Eli's concerns, you could use xasprintf, but
make sure you xfree() the memory allocated by it.
