--- Comment #13 from Murugesan Nagarajan <murugesandins at gmail dot com> --- MY LAST COMMENT: I agree. Normally I used to handle bug fix using following ways: 1. Steps to reproduce to issue creating core dump files. There are some other ways which may work(Example: -pthread or -lmurugesanopenssl or -lrfcsdk or -lnwrfcsdk or ... options) After this I used to receive/send that test result to/from test/development team. Few libraries I faced a lot of errors during 2008 to 2013 and FEW of them(I guess 4 out of six) were fixed during. 2. Hence I reported this error at current(old version) library. I agree that it is working when we use -pthread. However, this may report some other issue in future.
