We plan to fix the issue in 1.8. 46751 4 leimaohui 2014-11-05 01:38:09 +0000 I changed the gcc from 4.9.1 to 4.9.2 in yocto,and tested these cases. The results are the same. 46892 5 leimaohui 2014-11-10 06:11:19 +0000 I changed the gcc to 4.8.1 in yocto 1.7,these bugs disappeared. So I think it was gcc 4.9.1 caused these bugs. 47243 6 leimaohui 2014-11-28 09:16:03 +0000 I found the reason is the founction "pthread_exit(0)" can't execut normally。 Because it will lead a SIGABRT signal and aborted .
