--- Comment #3 from Davide Italiano <dav...@freebsd.org> ---
This was also fixed by my last commit.

commit 1567395d7e7cc2bb203821cb2329b79255bc8a0a
Author: davide <davide@91177308-0d34-0410-b5e6-96231b3b80d8>

    [NewGVN] Create a StoreExpression instead of a VariableExpression.

    In the case where we have an operand defined by a lod of the
    same memory location. Historically this was a VariableExpression
    because we wanted to make sure they ended up in the same class,
    but if we create the right expression, they end up in the same
    class anyway.

    Fixes PR32897. Thanks to Dan for the detailed discussion and the
    fix suggestion.
