[sr-dev] [kamailio/kamailio] Kamailio 4.4.5 segfault (redis_client) (#1853)

[Daniel-Constantin Mierla]

I think the problem is that you execute a command that has a specifier:

```
HDEL calls at nos.ventask.gw.gotelecom.pt 0%bW7101115050H%beGhEfDmAjC0f at LOS30.INTIMS.NOS.PT
```
Having %b expects an additional parameter and the backtrace indicates you use the function with (srv, cmd, result). There was a safety check for such cases with commit 75bbbe4059cb6fde4c74fa9157f400a24e6f7496 , but not sure if it is in 4.4.x. So you have to use the redis command where you pass the argument that has any % via additional parameter.

I am closing this one, because it seems to be related to something fixed (as a safety check) and you must ensure that the command you pass it doesn't have %X alone, without actually parsing the expected arguments.
