I have noticed that relatively recently the files from glibc that implement these functions (__cxa_atexit and __cxa_finalize) were removed from the tree, they weren't used anyway but i was going to try and have them build to get these functions in libroot for testing. Does anyone have any advice on what I could do to get implementations of them in libroot, either ones from the glibc we use bits of or elsewhere? Thanks Paul Davey
