SETI@home client Segmentation fault

After I compiled the seti@home client source without error message, I try to run it at standalone mode. But it always prompt out the error "Segmentation fault (core dumped)". I used gdb to run the compiled "setiathome-6.12.i686-pc-linux-gnu.debug".

it stops at TestBoincSignalHandling. The output is as follows, but I still don't know what the problem is...
Does someone know this? Thank you!

The "standalone mode" is only for testing purposes, you can't use it to get, process and return work (results) to SETI

Install BOINC
Add ("attach to" the) SETI@home project
(select "Yes, existing user" and use the same email & password from your SETI@home account)

The SETI@home applications and tasks will be downloaded automatically.
