SEGV signal occurred when running program thulac

[fCorleone]

When I try to run thulac and thulac_test program. I found this :

ASAN:SIGSEGV
=================================================================

I believe another issue occurred when I running train_c. The input file has been put at :https://github.com/fCorleone/fuzz_programs/blob/master/thulac/issue2_testcase. It's another SEGV signal issue:
