### Description
<!--
Explain what you did, what you expected to happen, and what actually happened.
-->
We are using kamailio with a python_handler. If a call is parallel forked, kamailio
segfaults in append_branch (get_str_fparam) because the q parameter is not set. Since the
q parameter is optional, we didn't set it. If I set something for q (eg
"1"), the forking seems to work fine.
I tested the issue with Kamailio 5.2.[238] and 5.5.4. The behavior is equal in all
versions.
We are using yocto dunfell as OS with compiler option "O2". Interestingly, if I
disable the optimization, the forking works even without q parameter.
### Troubleshooting
#### Reproduction
<!--
If the issue can be reproduced, describe how it can be done.
-->
The problem is reproducible. As soon as a call is forked to at least two callees, kamailio
crashes.
#### Debugging Data
<!--
If you got a core dump, use gdb to extract troubleshooting data - full backtrace,
local variables and the list of the code at the issue location.
gdb /path/to/kamailio /path/to/corefile
bt full
info locals
list
If you are familiar with gdb, feel free to attach more of what you consider to
be relevant.

### Possible Solutions
<!--
If you found a solution or workaround for the issue, describe it. Ideally, provide a pull
request with a fix.
-->
If I set a value for the optional parameter q, the forking works as expected
`msg.call_function('append_branch', ruri, "1")`. Without the q
parameter, it segfaults.

Using msg.call_function() should be avoided because is a hack to executed kamailio native
config functions and can lead to crashes and memory leaks. It cannot be made completely
safe due to custom optimisations done by kamailio native config interpreter, unless one
goes one by one for each functions and analyses all kind of parameters and combinations.
If you want to go that way, pull requests are welcome!
Otherwise, you should use the KEMI framework exported functions:

If you want to discuss more, then email to sr-users(a)lists.kamailio.org .
