[eclipse@xxxxxxxxx]

Hello folks,

mosquitto seem to segfault when reading
/var/lib/mosquitto/mosquitto.db. System is Debian stable, version is
1.4.10-3+deb9u3. The file is attached, since its rather small (< 4 KB).

$ mosquitto -h
mosquitto version 1.4.10 (build date Wed, 06 Feb 2019 17:03:31 +0000)

strace mosquitto -c /etc/mosquitto/mosquitto.conf

open("/etc/mosquitto/conf.d/mosquitto.conf", O_RDONLY) = 5
fstat(5, {st_mode=S_IFREG|0600, st_size=512, ...}) = 0
read(5, "password_file /etc/mosquitto/mos"..., 4096) = 512
read(5, "", 4096)                       = 0
close(5)                                = 0
getdents(4, /* 0 entries */, 32768)     = 0

read(3, "f:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:"..., 32768) = 32768
read(3, "f:ff:00:00:1e\", \"minor\": 30, \"ma"..., 4096) = 4096
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR,
si_addr=0x7fffc57db000} ---

Do you know what's wrong here?

Thanks in advance,
Jan
