Win32: How to crash?

Question

i'm trying to figure out where Windows Error Reports are saved; i hit Send on some earlier today, but i forgot that i want to "view the details" so i can examine the memory minidumps.

But i cannot find where they are stored (and google doesn't know).

So i want to write a dummy application that will crash, show the WER dialog, let me click "view the details" so i can get to the folder where the dumps are saved.

How can i crash on Windows?

Edit: The reason i ask is because i've tried overflowing the stack, and floating point dividing by zero. Stack Overflow makes the app vanish, but no WER dialog popped up. Floating point division by zero results in +INF, but no exception, and no crash.

Answer 1

You are assuming the memory dumps are still around. Once they are sent, AFAIK the dumps are deleted from the machine.

The dumps themselves should be located in %TEMP% somewhere.

As far as crashing, that's not difficult, just do something that causes a segfault.

Answer 2

Should be a good start:

int main(int argc, char* argv[])
{
   char *pointer = NULL;
   printf("crash please %s", *pointer);
   return 0;
}

Answer 3

Not sure if this will trigger the Error Reporting dialog, but you could try division by zero.

Answer 4

void crash(void)
{
    char* a = 0;
    *a = 0;
}

Answer 5

You guys are all so verbose! :-)

Here's a compact way to do it:

*((int*)0)=0;
