### 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.
