With Debian, you need to compile against TclTk 8.3.
(install the tcl8.3-dev and tk8.3-dev packages)

see debian bug #248105

Two more suspects for consideration:

#171353: tk crash if widget accessed from wrong thread

#201062: tcl8.4: Tcl_CreateInterp() creates a pipe and does not set handles to close on exec
