Fastest way to crash the VC++ compiler

[Bekas]

Just use this line (valid C++):

Code: Select all

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?

Just use this line (valid C++):

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.

[Bekas]

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!
}

[Klaim]

Wow, strange...

[nullsquared]

Talk about weird code...

Code: Select all

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


Compiles fine under GCC 3.4.1.

Confirmed This thread is genius...

[Klaim]

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.

[Klaim]

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.

Yey! We have a winner!
