RE: communication pattern causes corrupted data

I did a full recompile of the redhat 7.1 glibc explicitly setting
host=alphaev56-unknown-linux-gnu.  Just to be sure, I also recompiled
gm-1.6.3 and mpich-gm-1.2.4..8a.

The problem still occurs.

In doing some other tests, I have found that under gm-1.4/mpich-1.2..5
the problem does not exist under RH7.1.

Is gm-1.4+ allocating buffer space differently?  What else could be
going wrong here?
