Did I just win?

I broke msdev! :-)

C:\Documents and Settings\iago\My Documents\bak\My private projects\testprog\testprog.cpp(16) : fatal error C1001: INTERNAL COMPILER ERROR
  (compiler file 'E:\8168\vc98\p2\src\P2\x86\MDmisc.c', line 1244)
    Please choose the Technical Support command on the Visual C++

Error executing cl.exe.

Here's the code (I know it's stupid, the memset is wrong etc.):

Code Select Expand

#include "stdafx.h"
#include <stdio.h>
#include <stdlib.h>
#include <memory.h>

#define TRUE  1
#define FALSE 0
#define NULL  0

int main(int argc, char* argv[])
{
      char TestArray[0x7FFFFFFF];
      memset(TestArray, 1, 1);

      system("pause");
      return 0;
}

[iago]

hmm.. by doing this:

Code Select Expand

#include "stdafx.h"
#include <stdio.h>
#include <stdlib.h>
#include <memory.h>

#define TRUE  1
#define FALSE 0
#define NULL  0

char TestArray[0x7FFFFFFF];

int main(int argc, char* argv[])
{
      
      memset(TestArray, 1, 1);

      system("pause");
      return 0;
}
It compiles, but I get the error "Could not execute: Bad executable format(Win32 error 193)" when it tries to run :-D

Why the heck did you create such an enormous array? Just because you could?

[iago]

I wanted to time how long it would take to access that many elements of an array, realistically (if I used a loop and, say, 10 elements, caching would screw it up).

That's way over the maximum.
If you want to test access speed of a large block of memory, allocate like 100MB on the heap, not 2GB on the stack!
By making it global you probably confused the compiler enough for it to create an invalid file.

Yes, but at the time I didn't stop and think, "Hey, this is WAAAY too big!"  :-)

I don't think you can typically find 2GB of contiguous unused address space :p

Besides, without large address aware set, you can only allocate 2GB maximum (total).
