Hmm. No, I was using a clean tree. I tried
a50e63b38b931d945f97eac882278068221eca17 and the commit immediately before,
and the build problem showed up at a50e63b38b931d945f97eac882278068221eca17.
Let me re-apply the patch locally and try both gcc and clang (as the host
compilers).

I went back to a50e63b38b931d945f97eac882278068221eca17. There, my
release+asserts build failed, but my release-without-asserts build was OK.
I used clang-14.0.6 as the host compiler for both of these builds.
