That's why some people prefer to use Lisp, it has better debugging tools for that and stack traces are easier to use.
Still, debugging macro-using code IS harder. The first thing I need is full and partial macro expansion in the editor. There is a bit more then. When all fails I use an interpreter (most Common Lisp implementation have both an interpreter and a compiler) to follow the expansion process in detail.
If a supplied macro creates errors which are hard to understand, then it is also possible to request better compile time error reporting from the developers.
