Cppcheck: 'is_vertical_run' is assigned a value that is never used (vcl module)

Hello,

Cppcheck reported this:
vcl/coretext/salcoretextlayout.cxx
569     unreadVariable  style   Variable 'is_vertical_run' is assigned a value that
is never used.

    565                     bool is_vertical_run = false;
    566                     CFDictionaryRef aDict = CTRunGetAttributes( run
);
    567                     if ( aDict ) {
    568                         const CFBooleanRef aValue = (const
CFBooleanRef)CFDictionaryGetValue( aDict, kCTVerticalFormsAttributeName );
    569                         is_vertical_run =  (aValue ==
kCFBooleanTrue) ? true : false;
    570                     }

See

Should "vertical_run" variable just be removed or should it be used in a
way?

Julien
