Using Tcl/Tk 8.5.13 I get a bus error (tested with OSX 10.6.2 and 10.8.3) if I type the following test lines:
package require Tk
font configure TkDefaultFont -size 10
ttk::label .status -relief sunken
menu .mbar
menu .mbar.apple
.mbar add cascade -menu .mbar.apple
.mbar.apple add command -label hello
. configure -menu .mbar
font configure TkDefaultFont -size 12
The console log shows amongst others:

The complete log file is attached. Tcl/Tk 8.5.9 worked fine.
