Summary: Bindings in slave interpreter results in core dump

Initial Comment:
The following small script says all. If we uncomment
the first binding tcl segfaults, while the second is ok
(I don't understand why). This is not specific of
BWidgets, as several other widgets (pure scripts)
package shows the same behaviour.

#!/bin/sh
# show a bug found in tk, when running in a slave
interpreter
# Rildo Pragana <ri...@pr...> -- Recife, Brazil 2005
#exec wish "$0" "$@"

pack [button .b -text exit -command exit]

set code {
    package require Tk
    package require BWidget
# if the following line is uncommented, the interpreter
segfaults
#   bind . <Destroy> exit
    pack [ComboBox .cb]
#   ...but here it is ok!
    bind . <Destroy> exit
}

set test [interp create test_interp]
$test eval $code

This was discovered when trying to make SpecTcl support
more widgets. Most of the crashes was related to the
above bug, when trying to use the embedded test
feature. (see save.tk in SpecTcl)

Ick! That shouldn't happen...

(What version of Tk are you using?)
