In journalctl we don't run the static destructors defined via the STATIC_DESTRUCTOR_REGISTER() macro, since it requires a corresponding static_destruct() call. In most cases this is handled by the DEFINE_(TEST_)?MAIN*() macros, but journalctl defines its own main function, so let's handle that as well. $ valgrind --suppressions=valgrind.supp --show-leak-kinds=all --leak-check=full build/journalctl --no-pager -u system.slice -n 10 >/dev/null ==2778093== Memcheck, a memory error detector ==2778093== Copyright (C) 2002-2022, and GNU GPL'd, by Julian Seward et al. ==2778093== Using Valgrind-3.19.0 and LibVEX; rerun with -h for copyright info ==2778093== Command: build/journalctl --no-pager -u system.slice -n 10 ==2778093== ==2778093== ==2778093== HEAP SUMMARY: ==2778093== in use at exit: 8,221 bytes in 4 blocks ==2778093== total heap usage: 458 allocs, 454 frees, 255,182 bytes allocated ==2778093== ==2778093== 13 bytes in 1 blocks are still reachable in loss record 1 of 4 ==2778093== at 0x484586F: malloc (vg_replace_malloc.c:381) ==2778093== by 0x4DA256D: strdup (strdup.c:42) ==2778093== by 0x4ADB747: strv_extend_with_size (strv.c:544) ==2778093== by 0x405386: strv_extend (strv.h:45) ==2778093== by 0x40816F: parse_argv (journalctl.c:933) ==2778093== by 0x40EAB5: main (journalctl.c:2111) ==2778093== ==2778093== 16 bytes in 1 blocks are still reachable in loss record 2 of 4 ==2778093== at 0x484578A: malloc (vg_replace_malloc.c:380) ==2778093== by 0x484A70B: realloc (vg_replace_malloc.c:1437) ==2778093== by 0x4ADB2A3: strv_push_with_size (strv.c:423) ==2778093== by 0x4ADB620: strv_consume_with_size (strv.c:496) ==2778093== by 0x4ADB770: strv_extend_with_size (strv.c:548) ==2778093== by 0x405386: strv_extend (strv.h:45) ==2778093== by 0x40816F: parse_argv (journalctl.c:933) ==2778093== by 0x40EAB5: main (journalctl.c:2111) ==2778093== ==2778093== LEAK SUMMARY: ==2778093== definitely lost: 0 bytes in 0 blocks ==2778093== indirectly lost: 0 bytes in 0 blocks ==2778093== possibly lost: 0 bytes in 0 blocks ==2778093== still reachable: 29 bytes in 2 blocks ==2778093== suppressed: 8,192 bytes in 2 blocks ==2778093== ==2778093== For lists of detected and suppressed errors, rerun with: -s ==2778093== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0)
