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?
