Subject: Re: [OMPI users] OpenMPI-PGI: /usr/bin/ld: Warning: size of symbol `#' changed from # in #.o to # in #.so
From: Dmitry N. Mikushin (maemarcus_at_[hidden])

I checked that this issue is not caused by using different compile
options for different libraries. There is a set of libraries and
executable compiled with mpif90, and this warning comes for
executable's object and one of libraries...
