You may have already read this, but there is some discussion of
ref counts in the documentation that might interest you.

Well, you could download gdb for Mingw and install it. That
should at least be able to show you a backtrace of the crash.
You could also install Dr. Mingw and install it as the default
exception handler, it should also be able to show you a stack
trace. Without knowing where exactly the crash is happening,
there is not much I can suggest.

Did you run "make test" after building Tcl Blend? If not, try
it and see if the test cases are crashing.
