Subject: Re: [OMPI users] MPI_Allgather with derived type crash

Hi George,

Thanks a lot for your attempt! Possibly this is something OS specific? I'm
using CentOS release 5.4 x86_64 on the cluster. I also tried it on my
virtual box with CentOS 5.3 x86_64 (ompi 1.4.3). The same effect. On what OS
did you try? If it helps I can upload the virtual box image on my web site.
