[OpenSER-Users] openSER crashes while accessing emtpy pseudo-variable $fn in if-clause ?

[Rainer Strobel]

Hello,

while playing around with the pseudo variables whithin openser 1.2.1 I got a strange behavior.
I tried to check if the from-header-name of an invite message is set to 
(A|a)nonymous with an simple if-clause.


 if($fn =~"(A|a)nonymous") {
         ...do something ;
 }


It works fine while the from-name variable is not empty.
If the from-header-name in the INVITE message is not given openser crashes exactly on that comparison.

After that I started playing around using other comparisons, for example 'if($fn=~"foo")' or ' if($fn == "foo")' , with the same set-up.
Openser crashed each time processing that if-clause. 

I tested this with openser-1.2.1-notls on i386 openSUSE 10.2 with MySQL 5.0.26 and gcc 4.1.2

Can anybody confirm this problem ?

Debuggin informations are available and can be send additional if necessary.


Regards.
