You are right either the check can be move in the else block or disco should be checked for NULL before dereferencing it. Would you like to send a patch for this? You can either use bugzilla.redhat.com or upstream's bugs.freedesktop.org with product realmd component adcli to open a ticket and attache a patch. bye, Sumit > > Jocke > > On Wed, 2017-03-29 at 20:36 +0200, Joakim Tjernlund wrote: > > Got a BT now as well: > > ore was generated by `adcli -v info INFINERA.COM'. > > Program terminated with signal SIGSEGV, Segmentation fault. > > #0  0x000000000041087e in parse_disco_data (bv=0x7ffcbb9a7cb0) > >     at /var/tmp/portage/sys-auth/adcli-0.8.2-r1/work/adcli-0.8.2/library/addisco.c:384 > > > > warning: Source file is more recent than executable. > > 384 if (disco->client_site[0] == '\0') { > > (gdb) bt > > #0  0x000000000041087e in parse_disco_data (bv=0x7ffcbb9a7cb0) > >     at /var/tmp/portage/sys-auth/adcli-0.8.2-r1/work/adcli-0.8.2/library/addisco.c:384 > > #1  0x0000000001c8e706 in ??
