[mvapich-discuss] bus error in MPIDI_CH3I_CM_SHMEM_Sync

[Lana Deere]

I tried configuring with --enable-fast=O2,ndebug instead of O3,ndebug.  Now
I do not get the malloc warning and my simple send/recv test works.  I'm
getting segmentation violations in MPI_Intercomm_merge following
MPI_Comm_spawn, though.  I'll see what I can figure out about that.
