    hi, david, thanks for your kind suggestion, I have traced the code and fixed this issue by setting the LANG environment now. – bitchainer Feb 09 '17 at 06:27

After tracing the code of Cobalt, the cobalt need to get the posix_id by SbSystemGetLocaledId() in system_get_locale_id.cc, but the system didn't set the clang environment variable yet, and it get null which made the Crash, after setting the LANG environment variable(export LANG="en_US.UTF-8"), it works. Add CLANG environment variable
