--- Comment #21 from marcus at mc dot pp.se ---
For completeness, I tried building gcc 14.2.1 using
BOOT_CFLAGS="-O2 -fno-tree-vectorize"
and the build completed, successfully comparing stages 2 and 3
as equal (although I wouldn't trust the resulting compiler without
-fno-tree-vectorize).

So it's definitely the autovectorization that causes the FTBFS.
