Steps to reproduce: 1. Install sys-devel/binutils-2.20[gold] 2. Reinstall sys-devel/gcc-4.4.2 3. Run sys-apps/paludis-0.44.0 I was able to get paludis to run again by restoring /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.2/libstdc++.so.6.0.13 from a backup. Here's the output of gdb: gdb paludis warning: Can not parse XML syscalls information; XML support was disabled at compile time.
