[Pkg-systemd-maintainers] Bug#742322: backtrace for systemd crash

[Andreas Cadhalpun]

Hi,

I build systemd with debugging symbols and extracted a backtrace from 
the core dump:
#0  0x00007f1a0b51a75b in raise (sig=sig at entry=6) at 
../nptl/sysdeps/unix/sysv/linux/pt-raise.c:37

I hope this helps to fix the problem.

Best regards,
