I'm bumping into this too. Sigh. Suggestions?
Filed https://github.com/llvm/llvm-project/issues/63133 for the backport upstream. Please try applying https://github.com/llvm/llvm-project/commit/484e64f7e7b2c0494d7b2dbfdd528bcd707ee652 to sys-libs/libcxxabi.
(In reply to Dennis Nezic from comment #1) > I'm bumping into this too. Sigh. Suggestions? Workaround (if you don't want to try the patch I linked) is USE=clang on libcxxabi.
Can confirm that the patch works
This is an issue with libcxxabi-16.0.6 and gcc-13. Patch works
