I've written a blog post about printing custom data structures
from GDB using dlopen that I hope some of you find interesting
and I'd also be happy to discuss it:

Please let me know if there are any better ways to print data
structures like associative arrays from GDB, maybe by using
functions from the runtime library. Another exciting idea would
be to automate the pretty printing, maybe also by looking how the
pretty-printers for C++ in GDB 7+ are defined. I sadly haven't
read much D code from outside our company; is there a Phobos
function to automatically print expected and actual values for
failed assertions? In our company we use ocean's test!("==").
