I looked into this and found that there are two problems- the first
(which I can easily fix) is an error in our launch script;
unfortunately if I do that it still won't work, because the main
Matlab binary is wrapped with the MIT wrapper to log usage- the
resulting modification turns it into a script that gdb can't handle;
we're essentially back to the first problem.
There's no easy way around this, other than unwrapping Matlab which we
don't want to do. If it's important that you be able to run this so
you can debug someone's problem, I can temporarily make it possible
for you to access an unwrapped copy (for a few hours or so). I can't
do this until sometime Wd. afternoon or later as I'll be out Monday
and Tuesday. Let me know if and when you want to do this. I'd rather
not do it unless it's important.
Alex
