My asterisk.service is :

# cat /run/systemd/generator.late/asterisk.service
# Automatically generated by systemd-sysv-generator

[Unit]
SourcePath=/etc/init.d/asterisk
Description=LSB: Asterisk PBX
Before=runlevel2.target runlevel3.target runlevel4.target runlevel5.target
shutdown.target
After=network-online.target systemd-journald-dev-log.socket
nss-lookup.target local-fs.target remote-fs.target dahdi.service
misdn.service lcr.service wanrouter.service mysql.service postgresql.service
Wants=network-online.target
Conflicts=shutdown.target

[Service]
Type=forking
Restart=no
TimeoutSec=5min
IgnoreSIGPIPE=no

GuessMainPID=no
RemainAfterExit=yes
SysVStartPriority=2
ExecStart=/etc/init.d/asterisk start
ExecStop=/etc/init.d/asterisk stop
ExecReload=/etc/init.d/asterisk reload


My /etc/init.d/asterisk file is sourcing my /etc/default/asterisk which
includes an (uncommented) line COREDUMP=yes.
I also have
# grep core /etc/asterisk/asterisk.conf
dumpcore = yes

Is there a way to read Compiler Flags from a running system without looking
at source file directory ?

If someone forgets to select appropriate Compiler Flags, does it prevent
Asterisk to produce a core file (even an empty one) ?
