> FileFontStrike#initNative calls memset with LCDLUTCOUNT (the maximum length) as the number of bytes to zero out, which is incorrect as the elements are not 1 byte in size (unsigned char*), and will result in only part of the IG Table being correctly zeroed. This is more correctly resolved by passing sizeof igLUTable to memset instead.
