When I try to run a few tests in the sample directory in upscaledb with a litl script, I get a segment error, but I have no problem running the leveldb db_bench benchmark. How do I fix this problem? Please note that I did not make any code changes while testing.
Errors are as follows：
node1:~/lym/upscaledb$ /home/hpc/litl_ori/litl/libmcs_spinlock.sh ./samples/db1

it seems that a segment error occurred while calling real_pthread_init in the mcs_mutex_create function ,how should i fix this problem?
