I have this installed:
[ebuild R ] sys-power/powertop-2.2-r1 USE="X unicode" 0 kB
When I run it, it segfaults immediately. Running using gdb, I see this:
Program received signal SIGSEGV, Segmentation fault.
nl_cache_refill (sk=0x837f570, cache=0x837fd20) at cache.c:939
To get more detail, I'd have to figure out how to get ebuild to extract the source, so I could compile it manually, but I don't know how to do that.
Steps to resolve for now:
> echo "=dev-libs/libnl-3.2.15" >> /etc/portage/package.mask
> emerge -1 powertop
I believe this package has been masked in Portage and is propagating through the mirrors, so syncing tomorrow might as well solve the problem. Don't forget to remove the mask over time.
