From command prompt if I run:
# nmbd -s smb.conf
results in nmbd aborting.
# nmbd -s <some path>/smb.conf will not abort.
The problem appears to be in lib/pidfile.c, function pidfile_create() in lines:
short_configfile = strrchr( dyn_CONFIGFILE, '/');
slprintf( name, sizeof( name)-1, "%s-%s", program_name, short_configfile+1);
since there is no forward slash in dyn_CONFIGFILE, short_configfile = 0, which causes the subsequent call to slprintf to fail since address of second %s is 1.
