Package: rsyslog
Version: 8.2510.0-5devuan1
Severity: grave
Justification: renders package unusable

Hey,
since upgrading libc6 today, rsyslog fails with following message :

# /usr/sbin/rsyslogd -n -iNONE
/usr/sbin/rsyslogd: Relink `/usr/lib/x86_64-linux-gnu/libfastjson.so.4' with `/usr/lib/x86_64-linux-gnu/libm.so.6' for IFUNC symbol `modf'
Segmentation fault

dmesg :
rsyslogd[4291]: segfault at 9c ip 00007fb603e233a7 sp 00007ffe50362148 error 4 in libm.so.6[4b3a7,7fb603de9000+82000] likely on CPU 2 (core 0, socket 0)

after downgrading libc6, libc6-bin, locales to testing version (2.41-12) , rsyslog works again as it should.

thanks,
d.
