If `debug-on-error' is non-nil, Emacs will stop as soon as an error is
signaled, unless a `condition-case' catches it.  Otherwise you get the
complete backtrace.  What more than that do you want?  Are you asking for
some programmatic interface to what would be displayed if you didn't catch
an error?  If it's okay to look at things before an error is signaled, you
might be interested in `backtrace-frame'.
