% This code fails in Erlang R10B8 when debugger is running.
%
% Do the following:
% * Compile this module
% * Run "debugger_fun:test()", output is [yes,no,no,no]
% * Start the debugger "debugger:start" and interpret this module; no breakpoints etc. necessary
% * Run "debugger_fun:test()" again, output is now [no,no,no,no]

-module(debugger_fun).
-export([test/0]).

of R10B-9, probably to be released in December.
