What is the best way for me to reproduce it?

Did you build/use the dwt as a static lib? Build with what options? Or 
did you build with dwt just added to the include path?

dsss build test.d -debug -full

Can I use an existing example? can it be reproduces programatically?

No static lib. Built with -full -g -debug. I'll now try to use it as a 
static lib instead to see if that helps.

I catch MenuDetect in a tree, and call a function that removes the old menu 
and constructs a new one. Quite simple stuff.

I haven't found a way to reproduce it unfortunaly. It works at least 99% of 
the time, and I cant see any logic in the crashes. It could be a very rare 
combination of some sort, but I'll add more debugging info in the upcoming 
weeks, and perhaps then I can find out how it happens.

Sorry I cant be of much help. I have only just begun looking at dwt.
