I'm running the latest SVN version of Mono and the debugger installed to
/opt/mono-trunk on a Debian Lenny / AMD64 / Kernel 2.6.26.

Even a with a simple "Hello World", mdb causes a SIGSEGV as soon as I try to
run the program:

    [mono-trunk] /tmp @ gmcs -debug+ HelloWorld.cs
    [mono-trunk] /tmp @ mdb ./HelloWorld.exe
    Mono Debugger
    (mdb) run
    Starting program: ./HelloWorld.exe
    Thread @1 received signal 11 at #0: 0x7fffd85804d0.
    0x7fffd85804d0  int3
    (mdb) quit
    The program is running.  Exit anyway? (y or n) y
    Thread @1 exited.
    Process #1 exited.
    Target exited.

I've completely removed Mono and reinstalled it from the fresh compiled
SVN version.

The exact same SVN version works perfectly fine on 32bit.
