Name:
Torsten Rottmann

ReproducibleScript:
wish
% after 1 dfdf
after#0
% bgerror failed to handle background error.
    Original error: invalid command name "dfdf"
    Error in bgerror: invoked "break" outside of a loop

ObservedBehavior:
If you press "Skip Messages" ( the "return -code break" behaviour) former version of Tcl
didn't complain about "break outside a loop"

DesiredBehavior:
Same as in Tcl8.0: nothing



This behavior seems to have changed between 8.0.4 and 8.1.

Comment:
Still there in 8.3.2 in wish, but *not* tclsh of the same vintage with the following script:

  proc bgerror {msg} {puts "BGERROR: $msg"; return -code break}
  after 1 notacommand
  vwait forever

Something bizarre is going on here; moving this bug to Tk...
