I have found two bugs in R9B-1 on Windows XP Home
Edition.

The first crashes the compiler. The following little
program
demonstrates it.

---------------------------------------------------------------

-module(bug).
-export([bug/0]).
-record(rec,{f1}).

test()->
#rec{f1=queue.new()}.

---------------------------------------------------------------

133> c(bug).
./bug.erl:none: internal error in beam_clean;
crash reason: {{case_clause,{'EXIT',{function_clause,

[{dict,fetch_val,[4,[]]},

{beam_clean,find_all_used,3},

{beam_clean,module,2},
{compile,

'-select_passes/2-anonymous-2-',
2},
{compile,

'-internal_comp/4-anonymous-1-',
2},

{compile,fold_comp,3},

{compile,internal_comp,4},

{compile,internal,3}]}}},

[{compile,'-select_passes/2-anonymous-2-',2},

{compile,'-internal_comp/4-anonymous-1-',2},
{compile,fold_comp,3},
{compile,internal_comp,4},
{compile,internal,3}]}
error


---------------------------------------------------------------

The second bug crashes the debugger.
1, start the debugger
2, move the monitor window so that a part of the Title
bar of the
window is outside the screen.
3, move the mouse pointer down into the monitor window
again.

134> debugger:start().
{ok,<0.439.0>}
135>

=ERROR REPORT==== 23-Jul-2003::19:33:33 ===
Error in process <0.439.0> with exit value:
{badarith,[{dbg_ui_mon_win,handle_ev
ent,2},{dbg_ui_mon,loop,1}]}

You probably meant 'queue:new()', not 'queue.new()'.
Anyway, this has been fixed in R9C, so the compiler
does not crash. Instead you will see the warning
"function 'queue.new'/0 undefined".
