Hi all, a wonderful puzzle for the OSX folks in your team (Reproducer attached):
Attached source file builds with Xcode 7.0.0, but fails since the release of Xcode 7.0.1. I post it here since it results from an "if (MPI_COMM_NULL == MPI_COMM_SELF)". I am actually curious whether this is somehow off by itself, or whether it has something to do with how you define these constants. Overall, the situation is that this worked with previous clang compilers (and that it again works for more recent versions from mac-ports), so likely not your fault at all. The issue I get is: $ mpicc osx-10.10.5-xcode-7.0.1-openmpi-problem.c clang: error: unable to execute command: Segmentation fault: 11 clang: error: clang frontend command failed due to signal (use -v to see invocation) Apple LLVM version 7.0.0 (clang-700.0.72) Target: x86_64-apple-darwin14.5.0 Thread model: posix clang: note: diagnostic msg: PLEASE submit a bug report to http://developer.apple.com/bugreporter/ and include the crash backtrace, preprocessed source, and associated run script. clang: note: diagnostic msg: ******************** PLEASE ATTACH THE FOLLOWING FILES TO THE BUG REPORT: ... ******************** As I said above the culprit is "if (MPI_COMM_NULL == MPI_COMM_SELF)". Also, this doesn't works either: - "if (MPI_COMM_SELF == MPI_COMM_NULL)" But then, these work: - "if (MPI_COMM_SELF == MPI_COMM_WORLD)" - "if (MPI_COMM_WORLD == MPI_COMM_SELF)" So it appears it has something to do with MPI_COMM_NULL specifically. Maybe you already know of the issue. Maybe you can provide something to alleviate this issue in your releases, since it may take a while until we get a newer Xcode version on most OSX'es. My "ompi_info" is at the bottom of the mail. With that thanks for your looking into this, and many thanks for your wonderful MPI implementation, -Tobias $ ompi_info Package: Open MPI saibot@Tobiass-MacBook-Pro.local Distribution Open MPI: 1.8.4
