Summary: crash when getting the return value of b

Initial Comment:
Tcl Version: ActiveTcl v8.3.3

OS: Windows 2000 Pro SP2

Problem Behaviour:

The following code causes a crash:

namespace eval ::crashTcl {
  while {1} {
    set b [break]
  }
}

I know it doesn't make sense to take the return value 
of break... This is the simplified version of one of 
my scripts that calls a procedure (instead of break) 
which could return a value or force a break (return -
code break) It doesn't happen if the whole thing is 
not with a namespace eval.

this piece of code crashes with:

TclExecuteByteCode: done instruction at pc 14: stack 
top 0 != entry stack top -1 TclExecuteByteCode 
execution failure: end stack top != start stack top

Expected Behaviour:
b should not be assigned any value
break should work as expected, breaking out of the 
while
