    Fortran: Fix out of bounds access in structure constructor's clean up
[PR120711]

    A structure constructor's generated clean up code was using an offset
    variable, which was manipulated before the clean up was run leading to
    an out of bounds access.

            PR fortran/120711

    gcc/fortran/ChangeLog:

            * trans-array.cc (gfc_trans_array_ctor_element): Store the value
            of the offset for reuse.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/asan/array_constructor_1.f90: New test.
