[theuni]

Clang is unable to compile the Transform function for that combination of options.

Fixes #29801.

Ping @achow101. Sorry this took so long!

Concept ACK - Think I prefer fixing this inline, than in global flags / build. I guess we didn't end up making an issue upstream (https://github.com/llvm/llvm-project/issues)? If there is something to link to, would be good to add it here.

Checked this (./configure --enable-debug --with-sanitizers=address CC=clang CXX=clang++) works with Ubuntu clang version 18.1.3 (1) on x86_64.
