It looks like the debugger doesn't like try.
Loading the following module causes the debugger to crash.
%%%--------------------------------
-module(dbg_bug).
-compile(export_all).
oops() ->
try something()
catch
exception -> []
end.
something() -> 1.
%%%--------------------------------
It doesn't work in R10B-1, either.

Yes, we know. I am workin on that. Unfortunately it leads to
vast rewrites of the interpreter in the debugger, since all
of the code has to be aware of the different kinds of exceptions
that do exist now. Some code in the stdlib evaluator has to be
rewritten too. And it was a BIF that turned out to be missing
- to rethrow an exception with faked stackbacktrace.
So, I am on it, and will continue working after my christmas
holidays.
