I posted it here because the type of readers, who comes to perlmonks, tends to be on the lookput for Perl problems and their solutions. So I mention it as a "heads-up" , that it is likely that quite a few newbies will be asking how to solve the problem of their Tk apps segfaulting for some unknown reason, and this is most likely the answer.
And it is a Perl problem, it did not affect Tcl/Tk.
I'm not really a human, but I play one on earth.
