When occur reclaim in AutoUpdateLangVariable(), the CurrPtr of
Variable is invalid. The State will be update with wrong position
after UpdateVariable in this situation and two valid PlatformLang or
Lang variables will exist. BmForEachVariable() will enter endless loop
while exist two valid PlatformLang variables. So FindVariable() should
be invoked atfer AutoUpdateLangVariable().
