[Click] Problem while running OLSR on Click

[Abhishek Chanda]

Hi,

Thanks for the replies.
Here is the stacktrace:

(gdb) run test.click
Starting program: /usr/local/bin/click test.click
[Thread debugging using libthread_db enabled]
click: ../include/click/vector.hh:184: void*&
Vector<void*>::operator[](int): Assertion `i>=0 && i<_n' failed.

Program received signal SIGABRT, Aborted.
0xffffe410 in __kernel_vsyscall ()

) at click.cc:568

The file test.click has
FromDevice(eth0) -> Discard;
I will try to see if I can provide more information on this

Thanks
