[stgt] [BUG] Tgt-1.0.8 exited unexpectedly

[Hirokazu Takahashi]

Hi, 

It crashed at the same point.

I got a log and I want to send the whole of it to you. But the log is
rather large since it took a bit long to crash this time. I am not sure
I am allowed to post such a large message on this list.

How can I pass it to you? Should I send it to you directly?
I also have the core. I can also give it to you.

Thanks,
Hirokazu Takahashi.
