[ubuntu-mono] [Bug 408499] Re: mono has a needlessly executable stack

[Kees Cook]

It seems that mono actually does use the stack for execution, but only
when using the debugger.  :(

$ echo 'class MainClass { static void Main() { System.Console.WriteLine("Hello World!"); } }' > hello.cs
$ gmcs hello.cs
$ mdb ./hello.exe
Mono Debugger
(mdb) run
Starting program: ./hello.exe 
Cannot read symbol file `/usr/lib/mono/2.0/mscorlib.dll.mdb': Could not find file "/usr/lib/mono/2.0/mscorlib.dll.mdb".
Cannot read symbol file `/home/kees/hello.exe.mdb': Could not find file "/home/kees/hello.exe.mdb".
