The crash looks like: (gdb) bt #0 __strchr_sse42 () at ../sysdeps/x86_64/multiarch/strchr.S:136 #1 0x00007f41bf8af7bd in buffer_append_vf (buf=buf@entry=0x7f41bc91b7b0, ap=ap@entry=0x7f41bc91b788) at config-util.c:36 #2 0x00007f41bf8acd75 in daemon_reply_simple ( id=id@entry=0x7f41bf8aff5f "token_mismatch") at daemon-server.c:411 (gdb) frame 1 #1 0x00007f41bf8af7bd in buffer_append_vf (buf=buf@entry=0x7f41bc91b7b0, ap=ap@entry=0x7f41bc91b788) at config-util.c:36 36 if (!strchr(next, '=')) { (gdb) p next $1 = 0x500000000 <Address 0x500000000 out of bounds> The reason is that it loops getting a char* varargs argument until finding a NULL, that is not passed by the call in daemons/lvmetad/lvmetad-core.c: return daemon_reply_simple("token_mismatch", "expected = %s", state->token, "received = %s", token, "update_pid = " FMTd64, (int64_t)state->update_pid, "reason = %s", "another command has populated the lvmetad cache");
