Package: libopenmpi-dev Followup-For: Bug #1100120 We can see the spawn errors in the mpi4py 4.0.3-2 build logs, e.g. https://buildd.debian.org/status/fetch.php?pkg=mpi4py&arch=amd64&ver=4.0.3-2&stamp=1741705221&raw=0
Skipping the test_spawn tests, remaing tests pass but I get the following error locally (in pdebuild pbuilder chroot). It looks like a different variation of the OPAL ERROR I reported in this bug. But this backtrace refers to libucs.so.0. Could it a bug in ucx, which has just been upgraded to 1.18.1? The end of the build log is: ... test_starmap (test_util_pool.TestThreadPool.test_starmap) ... ok testConstructor (test_win.TestWinNull.testConstructor) ... ok testGetName (test_win.TestWinNull.testGetName) ... ok ---------------------------------------------------------------------- Ran 1813 tests in 58.573s OK (skipped=162) [sandy:25412:0:25412] Caught signal 11 (Segmentation fault: address not mapped to object at address 0x10) ==== backtrace (tid: 25412) ==== 0 /lib/x86_64-linux-gnu/libucs.so.0(ucs_handle_error+0x2bc) [0x7fd827e8064c] 1 /lib/x86_64-linux-gnu/libucs.so.0(+0x3182f) [0x7fd827e8082f] 2 /lib/x86_64-linux-gnu/libucs.so.0(+0x319fa) [0x7fd827e809fa] 3 /lib/x86_64-linux-gnu/libc.so.6(+0x3fdb0) [0x7fd82aa90db0] 4 /lib/x86_64-linux-gnu/libopen-pal.so.80(opal_net_get_hostname+0x12) [0x7fd827dd90a2] 5 /lib/x86_64-linux-gnu/libopen-pal.so.80(+0xfc518) [0x7fd827e0e518] 6 /lib/x86_64-linux-gnu/libopen-pal.so.80(+0xfc8a5) [0x7fd827e0e8a5] 7 /lib/x86_64-linux-gnu/libopen-pal.so.80(mca_btl_tcp_proc_create+0x464) [0x7fd827df8924] 8 /lib/x86_64-linux-gnu/libopen-pal.so.80(mca_btl_tcp_add_procs+0x6f) [0x7fd827df09cf] 9 /lib/x86_64-linux-gnu/libmpi.so.40(+0xf3c0c) [0x7fd8282f3c0c] 10 /lib/x86_64-linux-gnu/libmpi.so.40(mca_pml_ob1_isend+0x84d) [0x7fd8284841ad] 11 /lib/x86_64-linux-gnu/libmpi.so.40(ompi_dpm_dyn_finalize+0x1b5) [0x7fd828280575] 12 /lib/x86_64-linux-gnu/libmpi.so.40(+0x64c27) [0x7fd828264c27] 13 /lib/x86_64-linux-gnu/libopen-pal.so.80(opal_finalize_cleanup_domain+0x52) [0x7fd827d47ec2] 14 /lib/x86_64-linux-gnu/libopen-pal.so.80(opal_finalize+0x37) [0x7fd827d3a6b7] 15 /lib/x86_64-linux-gnu/libmpi.so.40(ompi_rte_finalize+0x14b) [0x7fd8282980eb] 16 /lib/x86_64-linux-gnu/libmpi.so.40(+0x9adfc) [0x7fd82829adfc] 17 /lib/x86_64-linux-gnu/libmpi.so.40(ompi_mpi_instance_finalize+0xbd) [0x7fd82829c3cd] 18 /lib/x86_64-linux-gnu/libmpi.so.40(ompi_mpi_finalize+0x21f) [0x7fd82829447f] 19 /usr/bin/python3.13() [0x45b262] 20 /usr/bin/python3.13(Py_Exit+0x2f) [0x69abef] 21 /usr/bin/python3.13() [0x68858b] 22 /usr/bin/python3.13() [0x6883fb] 23 /usr/bin/python3.13() [0x67ed22] 24 /usr/bin/python3.13() [0x67eb1e] 25 /usr/bin/python3.13(Py_RunMain+0x3c1) [0x67d961] 26 /usr/bin/python3.13(Py_BytesMain+0x2b) [0x63a72b] 27 /lib/x86_64-linux-gnu/libc.so.6(+0x29ca8) [0x7fd82aa7aca8] 28 /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0x85) [0x7fd82aa7ad65] 29 /usr/bin/python3.13(_start+0x21) [0x639ae1] ================================= python3.13:25412 terminated with signal 11 at PC=7fd827dd90a2 SP=7ffe028bd5d0.
