At least, it crashes on 32 bit.

BTW, this is quite strange, as I have one machine (x86_64) with 51 targets:

# tgtadm --op show --mode target | grep -c Target
51

Perhaps running an older tgt revision? Or 64 bit makes a difference 
here? I have no way to check if there is any limit on 64 bit right now.

It also crashes when tgtd is started in the foreground.
