The stack trace was really not that useful, but I did look into the 
dip-specific functions.

In the end I think I fixed it, but I'm not 100% sure how. I did some simple 
cleanup in the float sample conversion by applying a union used in one part of 
the code to another to replace a dereferencing cast. That seems to have helped, 
at least in my testing so far.
