The previous version is Ubuntu 16.04, everything is ok. But i found malloc corruption when my OS was upgraded to Ubuntu 17.04. I suspected the glib issue in previous, but i found the problem was caused by libjson-c after debugging. So i used the following command to rebuild libjson from souce: # apt-get source libjson-c3 # cd json-c-0.12.1 # sudo apt-get build-dep json-c # sudo debuild -i -us -uc -b i got 3 deb packages: libjson-c-dev_0.12.1-1.1_amd64.deb , libjson-c-doc_0.12.1-1.1_all.deb, libjson-c3_0.12.1-1.1_amd64.deb Then use cmd: dpkg -i <***.deb> to install the above package to overwrite(overinstall) the original libjson-c package . Last i rebuild my application and run , everything is ok. GCC verison: # gcc --version gcc (Ubuntu 6.3.0-12ubuntu2) 6.3.0 20170406 Copyright (C) 2016 Free Software Foundation, Inc.
