Dear Maintainer, I could reproduce the crash now in an minimal unstable VM with the given config and the command line from the coredumpctl output.
It seems that the function conf_parse_line is not prepared for missing quotation marks for the argument in the section head [1]. Therefore, if quotes are ommitted, the variable arg gets not filled, and therefore the cb->arg contains then a null pointer [2], that leads given to strcasecmp to the crash. @Miriam: I guess the crash should go away if change the config like following? - [ Server mirunas.mirulan.net ] - [ MountPoint /media/MiruNAS/Medienwerkstatt ] + [ Server "mirunas.mirulan.net" ] + [ MountPoint "/media/MiruNAS/Medienwerkstatt" ] Kind regards, Bernhard [1] https://sources.debian.org/src/nfs-utils/1:1.3.4-2.5/support/nfs/conffile.c/#L274 [2] https://sources.debian.org/src/nfs-utils/1:1.3.4-2.5/support/nfs/conffile.c/#L582
