Fix memory overrun in memset of m_anDctBlock #39

Closed vbaderks closed 6 years ago

vbaderks commented 6 years ago

m_anDctBlock is defined as signed short but initialized with a size of (64*sizeof(int)). Note 1: using sizeof is in general more safe as it not affected by changes elsewhere. Note 2: memory overrun had no effect in released product as following class member is also initialized with zero's.
