[SR-Users] kamcmd gives segmentation fault (5.0.4)

[José Lopes]

Hello Daniel,

Thanks for you reply.

I checked again and I am using the version 5.0.4 from the debian packages
for debian (bellow there is the output of some commands to confirm this).

I also reboot the machine, but i still have the same problem with the same
output on gdb.


Best Regards,
Jose Lopes
