[petsc-dev] cray warning - reduction in alignment ignored

[Hapla Vaclav]

I've got this with Cray compiler

          CC arch-daint-cray-opt/obj/dm/impls/network/network.o
CC-1160 craycc: WARNING File = /scratch/snx3000/haplav/petsc/include/petsc/private/dmnetworkimpl.h, Line = 20
  A reduction in alignment is ignored.
  } PETSC_ATTRIBUTEALIGNED(sizeof(PetscScalar));
    ^

Cray C : Version 8.7.3 (20180718184853_d127f1e88e6a577c0c4f008444940f2bcded38e8)
Total warnings detected in /scratch/snx3000/haplav/petsc/src/dm/impls/network/network.c: 2


Is it something fixable?

Thanks
