Thanks for the responce!

My configure string was:
./configure --prefix=/home/metalian/mpich2-install --with-arch=LINUX32 --enable-threads --enable-shared CFLAGS=-m32 CXXFLAGS=-m32 FFLAGS=-m32 FCFLAGS=-m32 |& tee c2.txt
It works perfectly with 7.1.G (after making 7.1.G working I decided to try 8.0.0rc)

Ubuntu 12.04 has gcc 4.6.3

Yes, of course, the same thing (ldd gave me this name to create symlink for, all other libs were also found).

>Then I ran Firefly using /opt/mpich2-1.5-gcc32/bin/mpiexec and got it running perfectly.  
The only difference is using /home/metalian/mpich2-install but $PATH contains it.

I don't know. How can I find this?

No output at all.

Output is the same ('Segmentation fault' and nothing more).

Once again, 7.1.G works fine in the same system.
