I suggest to copy your code, and then keep removing lines from your copy, making sure it keep showing the same compiler error. In some time you will probably be able to produce a small program, fit for this newsgroup or even for Bugzilla. (There are tools to do this reduction automatically in Python, I think).
You don't necessarily need fancy tools to do that – as I recently pointed out in another thread, the Tigris »delta« tool worked fine for me on several occasions (http://delta.tigris.org/). Just write a simple shell script looking for the error message in the compiler output, and delta will try to automatically reduce the file for you.
There is some room for improvement though when you have an actual lexer/parser available for heuristically determining what pieces of code to delete – this might be a nice demonstration project for a D parsing library.
