Mono debugger segfault on "start"

[Francois Trahan]

Binary package hint: mono-debugger

Before we start, here's some details :

***Sample Code (test.cs) :***
class main
{
    static void Main(string[] args)
    {
 System.Console.WriteLine("coucou");
    }
}

***Compile command :***
gmcs -debug+ test.cs

***Test 1 : mono.exe OK***
$ mono test.exe
coucou

Running the executable works just fine... When trying to debug, mdb systematically segfaults...

Here's my debug session :
$ mdb test.exe
Mono Debugger
(mdb) start
Starting program: test.exe
Thread @1 stopped at #0: 0x7fff0225e5d1.
0x7fff0225e5d1 add %al,(%rax)
(mdb) s
Thread @1 received signal 11 at #0: 0x7fff0225e5d1.
0x7fff0225e5d1 add %al,(%rax)
(mdb)

In other words, mdb segfaults before running my code.

On another machine (same setup) mdb works fine on the same files (joined).
