I cannot reproduce and valgrind does not complain for me.

Andreas, how do you configure your plain bootstrap?

In any case, this must be a very recent change, could you try reverting

        PR tree-optimization/100453
        * tree-sra.c (sra_modify_assign): All const base accesses do not
        need refreshing, not just those from decl_pool.
        (sra_modify_assign): Do not refresh into a const base decl.

I have to correct myself, it only fails on ia64 and riscv64 with plain
bootstrap.

OK, thanks, the bootstrap indeed succeeds on x86-64 but the resulting Ada
compiler  is broken, see PR tree-optimization/100453.

I have reverted the commit, so hopefully this is fixed (but I cannot verify
that at the moment).

I'm seeing the same failure in a 64-bit-default Solaris/SPARC bootstrap, while
32-bit-default SPARC is ok.
