[Bug runtime/5648] Unaligned access to memory in _stp_vsnprintf() on ia64

------- Additional Comments From mhiramat at redhat dot com  2008-05-01 00:05 -------
I've found that another code causes unaligned access on ia64...

$ sudo stap -m end1b -bv end1.stp  -o /dev/null
$ dmesg 
...
end1b: systemtap: 0.7/0.131, base: a000000204a20000, memory:
633752+71360+384+14000 data+text+ctx+net, probes: 2
kernel unaligned access to 0xa000000204ad5fee, ip=0xa000000204a23761
kernel unaligned access to 0xa000000204ad9fbe, ip=0xa000000204a23760
kernel unaligned access to 0xa000000204addf96, ip=0xa000000204a23761
kernel unaligned access to 0xa000000204ae1f66, ip=0xa000000204a23760
kernel unaligned access to 0xa000000204ae5f3e, ip=0xa000000204a23761

$nm end1b.ko | sort
...
00000000000035c0 T stp_print_flush
0000000000003800 t probe_1059

This time, ip was in stap_print_flush()...
