I can confirm this. There are even some more oddities observed here:

1) The warning regarding the AIX version only occurs on machines running 
the 64bit kernel when invoking "lsof". Machines running the 32bit kernel 
seem to be ok. Explicitly invoking "lsof64" results in that warning for 
both kernel types, along with the expected "lsof64: FATAL: compiled for 
a 64 bit kernel. The bit size of this kernel is 32." on a machine with 
the 32bit kernel (which is ok of course).

2) Occasionally I do see the aforementioned segfaults, but so far I 
haven't been able to determine under which circumstances they occur, 
i.e. reliably reproduce them.

3) The values in the "SIZE/OFF" column are incorrect for almost all 
output lines. On the 32bit kernel machines, they are far too large and 
look like some overflow, e.g.

init          1    root    0u  VREG       10,4 4398046512504    0 / 
(/dev/hd4)

while on the 64bit kernel machines they're zero, e.g.

init           1   root    0u  VREG       10,3             0    0 / 
(/dev/hd4)

This is the same with the previous lsof 4.61 built for AIX 5.1, BTW. It 
is important to note that these wrong size/offset values are seen on 
machines with TL04, i.e. bos.mp(64) being at 5.3.0.40. On machines with 
ML03 (bos.mp(64) at 5.3.0.33) it looks ok.

Anyone can reproduce this?

Markus
