Wildcard in servicegroup causes segmentation fault

[Bernd Adamowicz]

 message once bevore beeing a member of this list.)



Hi All,



I'm facing the problem, that the pre flight check from nagios causes
 a segmentation fault, if the 'member' variable of a servicegroup
 contains a '*' wildcard. I have just compiled the latest CVS tarball
 because there have been some similiar bugs reported, but it didn't
 fix my problem.



This is the part of my configuration that causes the problem:



# causes seg fault

define servicegroup{

        servicegroup_name   Swapspace

        alias               Services checking the swap space on
 disk

        members             BSS-MGMT-SMServer*,Swapspace



}



Of course there is at least one host which matches the pattern 'BSS-MGMT-
SMServer*,'.

Seems the '*' after 'BSS-MGMT-SMServer' causes the problem. If I
 switch to a single host name, everything works fine:



# causes no seg fault

define servicegroup{

        servicegroup_name   Swapspace

        alias               Services checking the swap space on
 disk

       members             BSS-MGMT-SMServer-Test04b,Swapspace

}



I run Nagios in GDB. This is the output:



>nagios-2-x-cvs/base # gdb nagios

(gdb) run -v /usr/local/nagios/etc/nagios.cfg

Starting program: /root/temp/nagios-2-x-cvs/base/nagios -v /usr/local/nag
ios/etc/nagios.cfg

Maybe this will give someone of you a hint, what might have happened.
 (I was a little bit confused about the last modified date of 05-31-2006,
 but I'm shure I got the latest tarball.)



Maybe someone has help. Thanks in advance.
