<tt>% This code fails in Erlang R10B8 when debugger is running.<br>
%<br>
% Do the following:<br>
% * Compile this module<br>
% * Run "debugger_fun:test()", output is [yes,no,no,no]<br>
% * Start the debugger "debugger:start" and interpret this module; no
breakpoints etc. necessary<br>
% * Run "debugger_fun:test()" again, output is now [no,no,no,no]<br>
<br>
-module(debugger_fun).<br>
-export([test/0]).<br>
<br>
<br>
n(N) -><br>
lists:map(<br>
fun(X) when N==X -><br>
yes;<br>
(_) -><br>
no<br>
end,<br>
[1,2,3,4]<br>
).<br>
<br>
test() -><br>
n(1).<br>
</tt><br>
<br>
If you replace the "when" clause in the fun with a case expression then
it works fine.<br>
