DATA MEMBERS Size

[Robertus]

I have a class with a data member of 128 KB (a character string)

class cmyclass
{
protected:
char buff[131072];
public:
//constructor
cmyclass(const char* pChar)
{
memset(buff,0,131072*sizeof(char));
strcpy(buff,pChar);
}
//destructor
}

the program crashes at runtime (I do not use malloc or new) in the RELEASE version; do you know why??

Isn't it possible to have members with bigger size than 64 KB ???

void main(void)
{
.....
cmyclass obj("John"
....
}

I would assume that it is this

char buff[131072];

OK, I assume the same thing, but WHY?
Why am I not allowed to have data members with a bigger size than 64K ???
(in debug mode it works, but in release it crashes)

had a similar problem but with buff[128].
what I did was char buff[128] = "".
Try it out.
