UNINIT4

Message        Byte offsets <start> to <end> of "<var>"<declared in>
               are 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 byte offsets of a variable have 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 full variable with values 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.
