PVS-Studio warning V512 for iecsdk

#define PL_MAX_PATH 255
typedef WCHAR TCHAR, *PTCHAR;
TCHAR pl_cvt_buffer[PL_MAX_PATH] = { '\0' };

int plh_read_pl_config_ini_file(....)
{
  ...
  ZeroMemory(
    pl_cvt_buffer,
    PL_MAX_PATH
  );
  ...
}

This is what should have been written here: PL_MAX_PATH * sizeof(TCHAR)


This suspicious code was found in iecsdk project by PVS-Studio static code analyzer.
Warning message is:
V512 A call of the 'memset' function will lead to underflow of the buffer '(pl_cvt_buffer)'. pl_csv_logger productivity_link_helper.c 683
