Description of problem: I've read the other bugs, and i feel like this is not the same problem. This has nothing to do with su or sudo, but happens with normal applications. Some programs no longer run, and give errors like these on startup: ./TeamSpeak.bin: symbol lookup error: ./TeamSpeak.bin: undefined symbol: initPAnsiStrings ./ut2004-bin: relocation error: ./ut2004-bin: symbol atexit, version GLIBC_2.0 not defined in file libc.so.6 with link time reference I also had other things not starting up, like ut99 and cedega games, but i didn't get a clear error message on that. None of this happens with the FC6 glibc. Version-Release number of selected component (if applicable): glibc-2.5.90-3 How reproducible: Always Steps to Reproduce: 1. Upgrade to newest glibc 2. Start up some affected programs (behavior found in teamspeak, ut2004, ut99 and cedega (not wine), and possible others) Actual results: The software doesn't load. Expected results: The software should run like previously Additional info:
