@alexfh I can't observe anymore the performance regression you reported on the original phab DR (q2.cc test case).

The original reduction doesn't compile anymore starting from clang-18, so I took the same base test and applied it to current libc++, but the memory usage and wall time are pretty close.

Let me know if you have an additional test case.
