[petsc-dev] CI error

[Mark Adams]

I get this error in CI with complex float:
https://gitlab.com/petsc/petsc/-/jobs/1170144554

I put in code earlier to fix this warning about uninitialized vars, but now
it does not seem to work:

/home/glci/builds-stage1/AbTGp5-t/0/petsc/petsc/src/ts/utils/dmplexlandau/plexland.c:414:94:
error: ‘col_scale[4]’ may be used uninitialized in this function
[-Werror=maybe-uninitialized]
2251 <https://gitlab.com/petsc/petsc/-/jobs/1170144554#L2251> PetscScalar
vals[LANDAU_MAX_Q_FACE*LANDAU_MAX_Q_FACE],row_scale[LANDAU_MAX_Q_FACE],col_scale[LANDAU_MAX_Q_FACE];

Yet I have code to initialize col_scale:

        for (q = 0; q < LANDAU_MAX_Q_FACE; q++) col_scale[q] = 0.0; //
suppress warnings

I get a similar error with an integer array.

Any suggestions?
