[erlang-questions] GS instability in Erlang tools

[Tim Bates]

Hi all,
When using the Erlang debugging programs, available via toolbar:start(), 
I frequently get the following:

GS frontend. Last mgs in was:{<0.118.0>,{destroy,2454}}
exit:{<0.118.0>,{destroy,2454}}
Reason: {'EXIT',
             {function_clause,
                 [{gs_frontend,
                      remove_objs,
                      [15,
                       {error,
                           {{badmatch,[]},
                            [{gstk_db,opt,3},
                             {gstk_gridline,delete,2},
                             {gstk,delete_only_this_widget,2},
                             {gstk,destroy_impl,2},
                             {gstk,doit,2},
                             {gstk,loop,1}]}}]},
                  {gs_frontend,doit,2},
                  {gs_frontend,loop,1}]}}

=ERROR REPORT==== 2-Jun-2007::16:59:55 ===
Error in process <0.36.0> with exit value: 
{{badmatch,[]},[{gstk_db,opt,3},{gstk_gridline,delete,2},{gstk,delete_only_this_widget,2},{gstk,destroy_impl,2},{gstk,doit,2},{gstk,loop,1}]}

This occurs when doing innocuous things such as clicking the 'Next' 
button in a debugger window and a few other circumstances that don't 
appear to be quite as repeatable.

I've seen this: 
http://www.erlang.org/ml-archive/erlang-questions/200604/msg00076.html
but that appears to be referring to errors in a user-developed GS 
application and not part of OTP.

I also get this:

Internal error... restarting.

=ERROR REPORT==== 2-Jun-2007::17:05:44 ===
Error in process <0.77.0> with exit value: 
{function_clause,[{lists,nthtail,[2,[]]},{tv_pg_gridfcns,resize_grid,3},{tv_pg,loop,1}]}

sometimes when attempting to resize the window showing the contents of 
an ets table in the Table Viewer.

I don't recall having these problems before R11B-4 but then I've changed 
to a new computer at roughly the same time so it could be related to the 
Erlang version or TK version (8.4.9 and 8.4.14) or even the hardware 
platform (AMD64 X2). Is anyone else having these problems?

Thanks in advance,
Tim.
