Hi, While trying to build a clean clone of SWI-Prolog from the master branch (commit 3a4bbb648abc5e23882742669c95c7976d194723), I’m seeing the following issues (excuse the verbosity): ```prolog ➜ build git:(master) ✗ ctest -j 8 --rerun-failed --output-on-failure Test project /Users/eshelyaron/forks/swipl-devel/build Start 68: bdb:bdb 1/1 Test #68: bdb:bdb ..........................***Failed 0.08 sec % PL-Unit: bdb ERROR: /Users/eshelyaron/forks/swipl-devel/packages/bdb/test_bdb.pl:84: test loop: received error: BDB: Error 46196288 on (0x102bf1a40): Unknown error: 46196288 ERROR: /Users/eshelyaron/forks/swipl-devel/packages/bdb/test_bdb.pl:96: test no_duplicates: received error: BDB: Error 46196928 on (0x102c1b0e0): Unknown error: 46196928 SWI-Prolog [thread 1 (main) at Mon Aug 16 11:11:23 2021]: received fatal signal 11 (segv) C-stack trace labeled "crash": [0] /Users/eshelyaron/forks/swipl-devel/build/src/libswipl.8.3.28.dylib(save_backtrace+0x112) [0x101a90f82] [1] /Users/eshelyaron/forks/swipl-devel/build/src/libswipl.8.3.28.dylib(sigCrashHandler+0xdb) [0x101a914ab] [2] /Users/eshelyaron/forks/swipl-devel/build/src/libswipl.8.3.28.dylib(dispatch_signal+0x235) [0x1019f7805] [3] /usr/lib/system/libsystem_platform.dylib(_sigtramp+0x1d) [0x7fff20516d7d] [5] /opt/local/lib/db53/libdb-5.3.dylib(__os_strdup+0x26) [0x102e0d852] sh: addr2line: command not found [6] /Users/eshelyaron/forks/swipl-devel/build/packages/bdb/bdb4pl.so(pl_bdb_open+0x4f0) [0x102bc1150] [7] /Users/eshelyaron/forks/swipl-devel/build/src/libswipl.8.3.28.dylib(PL_next_solution___LD+0xeacc) [0x1019880cc] [8] /Users/eshelyaron/forks/swipl-devel/build/src/libswipl.8.3.28.dylib(query_loop+0x16b) [0x1019d5efb] [9] /Users/eshelyaron/forks/swipl-devel/build/src/libswipl.8.3.28.dylib(prologToplevel+0x51) [0x1019d65d1] [10] /Users/eshelyaron/forks/swipl-devel/build/src/libswipl.8.3.28.dylib(PL_initialise+0x1c34) [0x101a21bf4] [11] /Users/eshelyaron/forks/swipl-devel/build/src/swipl(main+0x2a) [0x10177cf4a] [12] /usr/lib/system/libdyld.dylib(start+0x1) [0x7fff204ecf5d] Prolog stack: [24] bdb:bdb_open/4 [PC=1 in supervisor] [23] plunit_bdb:unit body/2 [PC=29 in clause 3] [22] system:setup_call_catcher_cleanup/4 [PC=5 in clause 1] [20] plunit:call_det/2 [PC=11 in clause 1] [19] system:catch/3 [PC=2 in clause 1] [18] plunit:run_test_6/6 [PC=68 in clause 5] [17] plunit:run_test_once/5 [PC=41 in clause 1] [15] plunit:run_unit/1 [PC=184 in clause 3] [14] plunit:run_unit/1 [PC=8 in clause 2] [13] plunit:run_unit_and_check_errors/1 [PC=4 in clause 1] [12] system:setup_call_catcher_cleanup/4 [PC=5 in clause 1] [10] plunit:run_tests/1 [PC=20 in clause 1] [9] test_bdb:test_bdb/0 [PC=8 in clause 1] [8] system:catch/3 [PC=2 in clause 1] [7] system:catch_with_backtrace/3 [PC=6 in clause 1] [6] $toplevel:run_init_goal/2 [PC=17 in clause 1] [4] $toplevel:run_init_goals/1 [PC=7 in clause 2] [3] $toplevel:initialise_prolog/0 [PC=94 in clause 1] [2] system:catch/3 [PC=2 in clause 1] [1] $toplevel:$initialise/0 [PC=12 in clause 1] [0] system:$c_call_prolog/0 [PC=0 in top query clause] Running on_halt hooks with status 139 Killing 52146 with default signal handlers 0% tests passed, 1 tests failed out of 1 Total Test time (real) = 0.09 sec The following tests FAILED: 68 -

Doesn’t reproduce. Just tried a clean build after upgrading Macports to the latest version for the dependencies. Tests run just fine. Using db62 from Macports. ---
