I posted a similar patch last month:

    http://sources.redhat.com/ml/gdb-patches/2002-08/msg00198.html

At that time you rejected it for the reasons given in:

    http://sources.redhat.com/ml/gdb-patches/2002-08/msg00214.html
    http://sources.redhat.com/ml/gdb-patches/2002-08/msg00235.html

Please explain what has changed between then and now which makes it
acceptable to now use frame_register_unwind()?

Puzzled,

Kevin
