This issue is more likely to be a library issue than a compiler
issue. For example, a Felix library uses Judy arrays, which are
digital tries (optimised page tables) .. actually it's the Felix
garbage collector. Trie's are useful data structures, but tries
keyed by pointers aren't compatible with Boehm unless you also
provide custom routines to scan them.
