tested on sifive unmatched (riscv64). Compilation went fine, but almost all tests segfault. seems it is not caused by oversubscribing. I append > import faulthandler > faulthandler.enable() in the first line and run mpiexec --oversubscribe --use-hwthread-cpus --mca btl tcp,self -n 1 python3.9 -B ./test/${test} -v for each test and obtained a full log in attachment mpi4py_test.out some excerpt of segment fault message: [unmatch8:908877] [[46553,0],0] ORTE_ERROR_LOG: Data unpack would read past end of buffer in file /var/tmp/portage/sys-cluster/openmpi-4.1.2/work/openmpi-4.1.2/orte/util/show_help.c at line 507 Fatal Python error: Segmentation fault Current thread 0x0000003fa8d18010 (most recent call first): File "/var/tmp/portage/dev-python/mpi4py-3.0.3/work/mpi4py-3.0.3-python3_9/test/test_attributes.py", line 224 in <module> -------------------------------------------------------------------------- Primary job terminated normally, but 1 process returned a non-zero exit code.

I reproduced this in amd64. Not sure if it is something with my environment or config, it fails on either mpich-3.4.3 or openmpi-4.1.2.ebuild.
