Hi Folks,
I am seeing a lot of errors when I run the full test suite (with latest
master) on my MacBook, related to SEGVs inside (or thereabouts)
PetscCommBuildTwoSided_Ibarrier. Do I have something mis-configured or ... ?
Sample error message below:

Hm - we primarily use default apple clang/clang++ with gfortran from brew.
And the nightlybuilds are fine [will have to check if something broke today]
There was previously an issue with gcc from brew - but don't remember what it
was.

Thanks, Satish. I'll give things a try using clang/clang++ to see if the
problem is related to the GCC I have installed.

Nope -
Reported to MPICH folks https://github.com/pmodels/mpich/issues/2437 and
ignored.
What about using Gnu compilers and OpenMPI (allegedly OpenMPI has fixed up
many of their ongoing bugs).

If you guys cannot walk down the hall and get them to consider these bugs,
we should just stop using MPICH and recommending
it to unsuspecting people. T
Things work fine when I use clang, but I'd really like to be able to use
GCC as well.
I updated the ignored issue to reflect that the bug is still present when
using GCC 7.1.0.
I suppose I will give OpenMPI a try when I get a chance.

This works fine.

This should be noted in the MPICH GitHub issues tracker.

GCC works great on Linux, but IMHO it is always problematic on Mac. I had a lot
of trouble when using GCC on Mac for netcdf, libmesh and some other stuff. And
it seems not easy to fix the problems on the library side. For example, the
netcdf problem I got has existed for several years, and there
10 matches
