Description Eric Smith 2010-01-16 10:33:28 UTC

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:

USE=gold on any version but the absolute latest (2.20.51.0.5 atm) is not supported
