Hi all,

I'm going to create an application that emulates different types of crashes...
So, can you guys help me by listing all known ways in which an application can crash?
For example,
The code:

char *p = 0; // Null pointer.
char x = 0;
*p = x;

Is an illegal write, which shows the error:

and the application will be closed...
Please help!!!

Hi,

Some other fun ways might include stack overflow (write an infinitely recursive function), consuming all available memory (infinite loop that mallocs), dereferencing a pointer that's uninitialized and copying over the return address on the stack. You can probably trigger an NX failure by trying to use an address you've malloc'd as a function pointer too, if your CPU supports it...

Yes, I have done all of these by accident at some point.

/(p.{2}l)/;$_=$1}$::b=~/(..)$/;print("$::a$::b $::c hack$1.");

There are almost as many ways as there are functions available to the programmer... Every program bug has the potential to cause a crash.

- Accessing uninitalized memory / wrong addresses. Null pointers, array bugs, pointer bugs etc.
- Jumping to wrong addresses / using invalid function pointers.
- Out of memory. Stack / global RAM / heap / program memory / HD memory...
- I/O errors. File handling, pipes/IPC, hardware I/O, registry I/O etc etc.
- Accessing corrupt hardware.
- Divide by zero.
- Deadlock bugs. Waiting for resources that are never released. Could be both hardware and software resources.
- Semaphore/mutex bugs. Multi-threaded programs that don't protect shared variables.
- Crashing the OS through wrong use of API functions.
- Doing dumb things in assembler, such as not stacking CPU registers before using them.
- And on and on and on...

Thank you very much for listing those...
