One thing to watch out for is that the memory can be recycled. I've been very confused whenever I've forgotten this. I have a hack for the GC (appended -- ancient enough that it probably won't apply) that makes it easy to notice when an object you are interested in is collected. IIRC I apply this before the first run, call ggc_watch_object for the thing I am interested in, and then see in what GC cycle the real one is allocated.
If what you are looking for survives such a change, postponing garbage collection so it won't happen till the crash can make things simpler.
