Examples of errors detected by the V620 diagnostic
V620. Expression of sizeof(T)*N kind is summed up with pointer to T type. Consider inspecting the expression.

V620 It's unusual that the expression of sizeof(T) kind is being subtracted from the pointer to T type. domnormalizer.cpp 277
const XMLCh *DOMNormalizer::integerToXMLCh(unsigned int i) const
{
XMLCh *buf = (XMLCh*)
fMemoryManager->allocate(15 * sizeof(XMLCh));
XMLCh *pos = buf + sizeof(buf) - sizeof(XMLCh);
....
}

V620 It's unusual that the expression of sizeof(T) kind is being summed with the pointer to T type. wsnes9x.cpp 6145
typedef wchar_t TCHAR;
INT_PTR CALLBACK DlgOpenROMProc(....)
{
....
TCHAR *tmp, *tmp2;
....
while(tmp2=_tcsstr(tmp, TEXT("\\")))
tmp=tmp2+sizeof(TCHAR);
....
}
Most likely this is what should be written here: tmp=tmp2+1;

V620 It's unusual that the expression of sizeof(T)*N kind is being summed with the pointer to T type. Scriver input.cpp 387
BOOL HandleLinkClick(....)

MoveMemory(tr.lpstrText + sizeof(TCHAR)* 7,
tr.lpstrText,
sizeof(TCHAR)*(tr.chrg.cpMax - tr.chrg.cpMin + 1));
