The strange thing imo. is that sys-libs/llvm-libunwind was not installed before. So it seems that re-emerging sys-libs/libunwind made it incompatible with sys-libs/libcxxabi-11.0.0-1, which then required sys-libs/llvm-libunwind as an alternative, which in turn failed. The only way to resolve the issue was to enable static-libs on sys-libs/libunwind and re-emerge it. Not that I understand the full consequences of this. But it seems strange and forces the static-libs also on zlib.

In the original case, you have sys-libs/libunwind in @selected. Do you need it there? I dare say Iade's case shows _more_ of a bug because it shows us packages which should likely depend on either, but not sure. Let's see what toolchain says.
Hm, I'd say it's the same behaviour. In both cases sys-libs/libcxxabi-11.0.0-1 tries to pull in sys-libs/llvm-libunwind-11.0.0[static-libs], because sys-libs/libunwind-1.5.0-r1 now has -static-libs, while sys-libs/libunwind-1.5.0, which was installed before, has static-libs and thus fulfilled the dependency from sys-libs/libcxxabi: RDEPEND=" libunwind? ( || ( >=sys-libs/libunwind-1.0.1-r1[static-libs?,${MULTILIB_USEDEP}] >=sys-libs/llvm-libunwind-3.9.0-r1[static-libs?,${MULTILIB_USEDEP}] ) )" The bug in my opinion lies in the fact that there seems to be no stable way to have sys-libs/libcxxabi with -static-libs. I tried this: 1) unmerge sys-libs/libcxxabi and sys-libs/libunwind. 2) set USE -static-libs for sys-libs/zlib, sys-libs/libcxxabi and sys-libs/libunwind 3) emerge -1 sys-libs/zlib 4) emerge -1 sys-libs/libunwind 5) emerge -1 sys-libs/libcxxabi This worked. But when doing an emerge -DuNav after that, it went back to requiring static-libs for sys-libs/libcxxabi

I brought in sync libunwind and llvm-libunwind to USE=-static-libs in https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=813d3bab893e257e2315cb9ba1c96dbb3c359179 I think nothing should pull in USE=static-libs for them by default. *** This bug has been marked as a duplicate of bug 760504 ***
sys-libs/llvm-libunwind and sys-libs/libunwind cannot be installed at the same time: sys-libs/llvm-libunwind ebuild has RDEPEND="!sys-libs/libunwind" Either one gets pulled in with static-libs by sys-libs/libcxxabi, which enforces static-libs because sys-libs/libcxx depends on it, which also has static-libs enabled by default. So there seems to be an entire chain of packages that depend on each other, and some of them have static-libs enabled by default, while for one of them (sys-libs/libunwind) that default was recently changed. So we can either try to figure out all those packages and manually override their default by setting -static-libs in package.use, or just override static-libs for sys-libs/libunwind. From a user perspective, the second one is more straight-forward. Or you do that for us and change the default for all those packages already in the ebuilds, of course :-)
