Re: [Linux-ia64] IP-relative calls in start.S and initfini.c

OK. So, I linked my application with -Wl,-relax (using
gnupro-2.9-000501p2) and run it on the new kernel
(2.3.99-pre6-000501-19smp). Now it goes past the _libc_main call but it
gets a SEGV in __do_global_ctors_aux (same a reported in message with
subject "ld failure"):

Program received signal SIGSEGV, Segmentation fault.
0x400000000158eb50 in __do_global_ctors_aux ()
(gdb) bt

(gdb) p/x $r1
$2 = 0x0

it looks like the gp got corrupted.
