UNINIT3

Message        Variable "<var>"<declared in> is fetched but not
               initialized<inlineinfo>.  And there may be other such
               fetches of this field that have not been reported in
               this compilation.

Description    The specified member of a struct variable has been
               used without being set.  This might not have been
               what you intended.  The algorithms that detect this
               situation only report it once for a given field, and
               not necessarily at the first use of the uninitialized
               value.

User Action    Provide the struct member with a value before the
               variable is used.  If you only provide a value for
               the use reported here, you may find that when you
               recompile your program another uninitialized use is
               detected.  It is best to initialize variables as
               close as possible to the point of declaration.
