unfortunately how to start the program in a debugger is not the
issue here. multiple pieces of our stack no longer even compile with
gcc on OSX, and GDB does not work with clang. So clang/lldb seems to
be the only viable option right now on OSX.<br>
<br>
I've seen related posts to this list and located 3 year old open bug
report on mpich.org(link below) with identical errors. This seems to
be an ongoing issue with mpich on OSX. In the mean time I've
switched to OpenMPI and found that our regression suite runs
cleanly, not sure what's going on with MPICH but will not be able to
do much else without lldb.<br>

<div class="">after upgrading to osx sierra and latest xcode
some of my regression tests crash in MPI calls, that's as
far as I've got as MPI init seems to fail when run in the
debugger. See below. Can any one advise how to run the
