I noticed that during bumping app-arch/rar to 7.01. Using app-arch/unrar-7 seems to cause a segfault while trying to unpack Winrar (For getting the SFX file for USE=all-sfx).

Using an older unrar version works.

Can Gentoo do anything here or is it worth to report to upstream?

Please try to get a backtrace, but I'd probably just report it upstream.
