Hi blueshycool,

What type of error are you seeing? Can you send the testcase and the
resulting stack trace or error/exception message?

Thanks,
Hinkmond

I have tried to get the stack trace, but I can't.
Only get 1 level of the backtrace, So I register SIGSEGV signal and catch it.
I get the crached function name CVMjniInvoke().
But I can't ensure because of the multi-thread program.

Hi blueshycool,

Can you try again using a debug build (CVM_DEBUG=true)? You should be
able to get more in the stack trace. Please copy & paste whatever stack
trace you get with a new debug build and send it in to the forum so that
we can see what you are seeing.

Thanks,

Hinkmond
