Attempts to compile devel/llvm13 on a Pi4 running -current (updated on 20220126) with 8 GB of RAM and 8 GB of swap has failed on two occasions using make -DBATCH > make.log & in /usr/ports/devel/llvm13 using the system compiler. The system is self-hosted. The first failure reported clang error 139, but the second was different, reporting only: FAILED: tools/flang/lib/Evaluate/CMakeFiles/obj.FortranEvaluate.dir/check-expression.cpp.o along with a console report of +swap_pager: indefinite wait buffer: bufobj: 0, blkno: 1258432, size: 4096 +swap_pager: indefinite wait buffer: bufobj: 0, blkno: 627221, size: 8192 +swap_pager: indefinite wait buffer: bufobj: 0, blkno: 240419, size: 4096 +swap_pager: out of swap space +swp_pager_getswapspace(12): failed +pid 61012 (c++), jid 0, uid 0, was killed: failed to reclaim memory Swap use peaked a little over 50%. After the first failure a restart of make using MAKE_JOBS_UNSAFE=yes ran to completion with one thread. A copy of the build log, logging script and other notes is at http://www.zefox.net/~fbsd/rpi4/20220127/ Clang error 139 has been seen several times during make buildworld on a Pi3 running stable/13 with 2 GB of swap as well. Perhaps the two failures are related. The Pi3 failures didn't report out of swap, all were clang error 139 with "failed to reclaim memory". Even with only 1 thread (j1) the failure reproduced. Thanks for reading, bob prohaska 20220127
