The problem is not there.
I put a "free" and check for return value of malloc but still have the
segfault. (source code updated in attach)
I discovered that array size to send is limited to 64kB. If I send
8192 x double : it's ok. But more will cause segfault. I also changed
in order to send float than double: In that case, I can send an array
of 16384 float (64kB) but no more.
Is there a parameter when building OpenMPI about packet size ??
