Package: openmpi
Version: 1.3-1
Severity: serious

Hello

I just upgraded to openmpi 1.3-1. The compilation of my codes went fine.
The linking stage sometimes failed with

undefined reference to `MPI::Win::Set_errhandler(MPI::Errhandler const&)'
undefined reference to `MPI::Comm::Set_errhandler(MPI::Errhandler const&)'

in some external libs (trilinos) using openmpi 

When linking is ok, runtime fails with for example

symbol lookup error: /usr/lib/libHYPRE_FEI.so.2.0.0: undefined symbol: 
_ZN3MPI3Win14Set_errhandlerERKNS_10ErrhandlerE   

After playing with nm I got

nm /usr/lib/openmpi/lib/libmpi_cxx.a                                           
00000000 W _ZN3MPI6Status9Set_errorEi                                       
00000000 W _ZNK3MPI3Win14Set_errhandlerERKNS_10ErrhandlerE                  
00000000 W _ZNK3MPI4Comm14Set_errhandlerERKNS_10ErrhandlerE                 
00000000 W _ZN3MPI6Status9Set_errorEi                                       
00000000 W _ZNK3MPI3Win14Set_errhandlerERKNS_10ErrhandlerE                  
00000000 W _ZNK3MPI4Comm14Set_errhandlerERKNS_10ErrhandlerE                 
00000000 W _ZN3MPI6Status9Set_errorEi                                       
00000000 W _ZNK3MPI3Win14Set_errhandlerERKNS_10ErrhandlerE                  
00000000 W _ZNK3MPI4Comm14Set_errhandlerERKNS_10ErrhandlerE                 
00000000 W _ZN3MPI6Status9Set_errorEi                                       
00000000 W _ZNK3MPI3Win14Set_errhandlerERKNS_10ErrhandlerE
00000000 W _ZNK3MPI4Comm14Set_errhandlerERKNS_10ErrhandlerE
00000000 W _ZN3MPI6Status9Set_errorEi
00000000 W _ZNK3MPI3Win14Set_errhandlerERKNS_10ErrhandlerE
00000000 W _ZNK3MPI4Comm14Set_errhandlerERKNS_10ErrhandlerE
00000000 W _ZN3MPI6Status9Set_errorEi
00000000 W _ZNK3MPI3Win14Set_errhandlerERKNS_10ErrhandlerE
00000000 W _ZNK3MPI4Comm14Set_errhandlerERKNS_10ErrhandlerE

which mean that the missing symbol is registered as a weak symbol.

PS: I have -lmpi++ -lmpi at the linking stage and libmpi_cxx.* are present in 
/usr/lib/openmpi/lib

Am I missing something with 1.3? shouldn't it be a drop in replacement ?
