segfault in tgtd

Hello there,

We've been evaluating the tgt version 1.0.38 on a 64bit Linux kernel
(version 3.2.0-39-generic) in an Ubuntu installation. Occasionally, we
get a segmentation fault in tgtd and it's not clear what went wrong or
how to get more information in order to investigate the root cause.

All I get to see is lines like the ones below in the kernel log:
Jan 21 07:03:40 test-machine kernel: [2744939.501604] tgtd[12887]:
segfault at 0 ip 00000000004076aa sp 00007fffe0bcfa40 error 6 in
tgtd[400000+43000]
Jan 21 07:04:04 test-machine kernel: [2744963.554504] init: tgt main
process (12887) killed by SEGV signal

Is there any documentation out there or any other type of information
on some tgt diagnostics I could use to investigate this?

Thanks,
Alban
