Fortran compilation - alignement of symbol issue

[thomasgillis]

Dear developers,

I encountered the following warning during the link step of the samples in fortran:

mpif90 -I../../include -I/vagrant/soft/fftw-3.3.8-intel_2019.04/include  -g   -o test1D_cos_f test1D_cos.o wrap.o p3dfft++.o -lm ../../build/libp3dfft.3.a -L/vagrant/soft/fftw-3.3.8-intel_2019.04/lib -lfftw3 -lfftw3f  -lstdc++

The compilers I use are the intel 2910.04 for c,c++ and fortran.

Do you have an idea of how to solve it?

Thank you very much for your help.
