minfo.x is the small C component of padb that loads the MPI-provided debugger DLL and queries processes to get the message queues, this error message is coming from the MPI library in ompi/debuggers/ompi_common_dll.c:61.  It likely represents a build problem with OpenMPI.  Possibly that you are using static libraries and the correct symbols aren't being exported correctly?  If there was no information available or you are simply not using MPI padb is much better at reporting correct error messages, I suspect that the DLL is warning about missing data but then just using the values anyway and segfaulting which is why you are getting the Bad exit code message.

The rest of the padb functionality should be un-affected.
