I have an application which calls MPI_Probe. Strangely enough, the call leads to a crash with signal 6.
I am using OpenMPI-1.6, built using gcc-4.6, running on Linux-3.23.

(2). stack-trace: The relevant stack-trace, (http://goo.gl/HW0kM)
(3). watch-expressions: Related watch expressions in the debugger window (http://goo.gl/ejl7d)
(4). top-level-call: The point in the user-application where MPI_Probe is
I do not understand the cause, and I'd appreciate any help.
