Hi Daniel and welcome to the Chicken mailing list. Another thing to keep in mind is that the Chicken garbage-collector will move objects around during gc. That can cause a lot of hard-to-find bugs, and is probably one of the reasons for Joerg advice on not calling back into Scheme from your foreign-lambdas.
Another cause of problems with the relocations is that you cannot reference Chicken objects in C long-term, because the gc won't be able to update those pointers. Having said that, the ffi in Chicken is really nice to use, so much that I often use it to explore new C api's. And also, I sometimes use valgrind to check for memory leaks. Best of luck! K.
