Since _tcscpy_s is expanded to wcscpy_s call in Unicode version, you must specify the size of destination buffer in 2-byte unicode characters, not in bytes. Universal solution can look like this:

_tcscpy_s(array,
sizeof(array) / sizeof(TCHAR),
strText);



You got halts even if the source string was short enought, because -- in Debug version -- this function fills the buffer with 0xFD value.
