(After some chatting with Miguel Sofer in Tcler's chatroom)

It's likely a documentation bug. It isn't clear from the docs that the
first thing you have to do is calling TclInitSubsystems(). It is
possible only indirectly via calling Tcl_FindExecutable() or
Tcl_CreateInterp(). So, adding any of these two function calls at the
very beginning of main() makes crash gone.

for more detailed explanation.
