Interesting; but that one's dealing with the SHARED case, isn't it? In my case everything's statically linked so circular relocations between libc and lib*user aren't an issue; but on the other hand we need to run __thread_set_state (and other MIG routines) super early, unlike in SHARED. > > VM_MAX_USER_ADDRESS, which is defined to VM_MAX_ADDRESS, which is then > > defined to 0xc0000000, same as on i386.
