+[PATCH] LAUNCH: Fix mpcrun --help crash with NVDIMM
+author: Remi Dehenne
+
+mpcrun --help no longer crashes when mpc_print_config displays
+`<Topology> NVDIMM Found ! (OS Device #xx)` messages.
+Those messages are now printed on stderr with
+mpc_common_debug_log, rather than with fprintf on stdout.

+Subject: [PATCH] RMA: Fix invalid arg type in MPI_Win_get_attr
+
+The attribute_val argument of MPI_Win_get_attr was improperly set regarding
+to the MPI Standard.
+Prior to casting, the attribute_val argument must be an int** or void**.
+MPC assumed attribute_val to be an int* or void*, thus leading to
+unexpected behaviors in user applications.
