Summary: Tcl Scripts results in "called Tcl_FindHashEntry on deleted"

Initial Comment:
Tcl Version: 8.5.11
OS Platform and Version: Windows 7 (64 bit) & Linux (32 bit)
Thread Package: 2.6.6 (Linux) & 2.6.7 (Windows)

Problem Behavior:
- If script execution has finished the following output appears: called Tcl_FindHashEntry on deleted
- Additionally, under Linux a core dump is created

Expected Behavior:
- A clean finalization of Tcl interpreter

Tcl-Script:

package require Thread

set th1 [thread::create {puts worker_running ; thread::wait ; puts worker_stopped}]

thread::send -async $th1 {puts script_started; after 5000; puts script_done} go

puts "waiting for go..."

vwait go

if { [thread::exists $th1] } { 
    thread::release $th1
    puts worker_released
}

puts main_done
