1) Does this also affect libunwind-1.2.1 ?
2) emerge --info please!

This bug is quite stale but someone just added themselves to CC.

If it's still happening, please attach a fresh full build.log and emerge --info.

Seems this package was recently added as a dependency of stable net-fs/samba, so now I am hitting this bug ton x32 too
