NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

Thanks for the bug report. These are known failures with GCC 7 and we are working to resolve them. In the mean time (the next release) we will have an additional build flag that toggles tests known to fail to developers when building with GCC 7.

• async_comp_alloc: Known failure because this test is for a new feature (allocatable components of coarray derived types) which is only partially implemented and experimentally supported for now (gfortran 7 regression: no type conversion before coarray put #292)
• convert-before-put: Regression because the responsibility for type conversion during coarray puts was shifted from GFortran to OpenCoarrays. (Implement asynchronous allocation of components in derived typed coarrays and caf_is_present #260)

See also #342

I'm going to close this as a duplicate of #342, #292 and #260

If the opencoarrays policy is to have "known failures", Homebrew will have to build without build-time tests, I'm afraid.

no, we're going to add a flag to disable the tests with known failures (#342)

that way homebrew and users can still run the build-time tests.... I'm going to get a release out ASAP probably later today with this change

https://github.com/sourceryinstitute/OpenCoarrays/releases/tag/1.8.10 should be GCC 7/Homebrew ready
