Hi. New to this list. If this has been answered/resolved already, please point me to the solution. In a very recent update to CentOS 7 libstdc++ has been altered in a way that has removed CXXABI_1.3.8 and GLIBCXX_3.4.20. I've noticed that this has broken a number of executables linked on other systems that used to run on CentOS 7. Is there any fix for this short of backing off the update? Ubuntu seems to still allow these broken images to run. But I want the solid reliability CentOS has. If somebody can give me examples of Ubuntu up and running actual programs for a year plus then I'll gladly switch. I've never heard of Ubuntu dong that. I have had CentOS do that for me.
