[Spice-devel] [PATCH spice 08/12] Avoid jumping across variables declarations with initializers

From: "Daniel P. Berrange" <berrange at redhat.com>

If a 'goto' statement jumps across a variable declaration
which also has an initializer, the variable is in an undefined
state. Splitting the the declaration & initialization doesn't
change that, but the compiler can at least now detect use of
the unintialized variable
