Just use this line (valid C++):

class {} (x);

And the shortest "crasher":

Code: Select all

class{}(

Just 8 characters. I challenge you to crash VC++ with less than 8 chars

I guess you mean the compiler has an error, or?

What version btw?

That's valid c++? What on earth is it supposed to do?

I'm guessing it's synonymous with the valid C++ declaration for a structure of size 0, and it defines an instance named 'x'. I really don't know what it's meant for, but I know GCC supports it. At least that's what I remember reading somewhere.

I've encoutered cases where vc9 and vc8 crashes but can't remember how. I think it involved template code.

Crashes as in when you try to compile a "Microsoft (R) C/C++ Optimizing Compiler has encountered a problem and needs to close. We are sorry for the inconvenience." window pops up.

Tested on 7.1, 8, and 9 versions.

Declares a variable 'x' with anonymous type 'class {}'. It's similar to this:

Code: Select all

struct { int a; } x;

But with redundant parentheses around x.

Well that's something. I've had internal compiler errors before but never even heard of code crashing the entire application. That's quite a find.

Oh

this is hilarious.

Visual Studio 2008, now with improved download size and better crash rates. Get your copy today!

johnhpus> It only crashes the compiler execution, so if you're using visual studio it don't crash all the ide, only interrupt the code compilation.

And while we are on the subject, does anybody have any GCC "crashers" ?

This is not a crasher but here's a weird behavior from GCC:

Code: Select all

void f() {
  typedef int SomeType;
  int (x)[SomeType];  // no error from GCC!
}

Wow, strange...

Posted: **Mon Oct 06, 2008 3:30 am**

Talk about weird code...

Code: Select all

class _{}(x);main(){_(x)[_];}

Compiles fine under GCC 3.4.1.

Confirmed

This thread is genius...

Err....i don't understand...it don't crash here...

did you install the VS SP1? i did.

I'm on VS2005, with SP1 and the Vista patch. I created a Win32 console app, put in that line of code, and got an internal compiler error. The IDE survived, though.

Posted: **Mon Oct 06, 2008 11:05 pm**

Ah yes, VS2005 SP1 + XP here and it crases

But on VS2008 SP1 + XP (and maybe minor updates via Windows Update) it don't...

I don't have anyways to crash the compiler. But crashing the Form Designer is pretty easy with CLI/C++.. at least from what I've seen.

* Method 1: Have a nested enum in a C# assembly UserControl also used as a property of that Control. Caused a Designer out of memory exception while trying to load the control in designer when the control used in a CLI WinForm class.

* Method 2: open a CLI Winform class in the designer, than edit the .h file. Designer will crash on that form until you restart visual studio.
