[mpich-discuss] osx sierra troubles mpich 3.2

[Seo, Sangmin]

Hi Burlen,

You’re right. The same issue has been sitting there for a long time. We added your error case to the github issue (https://github.com/pmodels/mpich/issues/2063, we migrated all trac tickets to github), and we are investigating the issue. You can subscribe on the issue page if you’d like to get notifications about the issue.

Thanks,
Sangmin

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.

I've seen related posts to this list and located 3 year old open bug report on mpich.org<http://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.

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 program in the debugger on osx sierrra?
