Hi all,

I'm trying to debug a Squeak VM I built using GDB. However, I can't even start up Squeak:

Do I have to compile the VM differently in order to get it to work?

OK, I found out I *can* debug it if I start the VM normally and then attach GDB to the running process...

I kinda wish I had tried this earlier ;-)
