Ok, the problem is solved. I add a patch to my binutils2.20.1. The patch is

Hi,
Thanks for the help and reply!
It crashes when tcsd was trying to touch uclib, but I didn't do anything no
uclibc.
Below is the strace output:

Hi George,
I have just updated my openssl from OpenSSL 1.0.1e-fips to OpenSSL 1.0.1j. I
would start tcsd without a problem.

So you can run in GDB, but the moment you step into main() it crashes? (or
before?) Can you paste your console output so that we can see what commands,
exactly, were run?
Also, if you can get tcsd to crash from within GDB, please post the output
of the "bt" (backtrace) command.
Thanks,

We're testing with OpenSSL version 1.0.1f-1ubuntu2 on Ubuntu 14.04 and
OpenSSL version 0.9.8za on Mac OS X.
What is your operating environment? Are you able to run tcsd within gdb and
get a backtrace?
