Hi,
I am experiencing several fancy bugs with ORTE.
All bugs occur on Intel 32 bits architecture under Mac OS X using gcc
4.2. The tested version is todays trunk (it also have occured for at
least three weeks)
First occurs when compiling in "optimized" mode (aka configure
--disable-debug --with-platform=optimized) and does not occur in debug
mode.

Bus error
The other one occurs when running MPI program without mpirun (I know
this is pretty useless but still ;) ). This bug does not require
specific compilation options to occur. Running mpirun -np 1 mympiprogram
is fine, but running mympiprogram fails with segfault in MPI_Finalize:
~/ompi$ mpirun -np 1 mpiself
~/ompi$ gdb mpiself
