### Description

<!-- Explain what you did, what you expected to happen, and what actually happened. --> Im getting frequent log entries like this: `CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f19a3edec68), called from tls: tls_init.c: ser_free(323), first free tls: tls_init.c: ser_free(323) - ignoring`

This on a fresh VM running Ubuntu 22.04 LTS on the 5.6 branch (building latest release tag)

As well as that log message being printed on a frequent basis (every 2 to 3 mins) i am experiencing random crashes/restarts of kamailio. Looking at the core dumps tls_init seems to precipitate the core dump.

I have tried using both the TLS module, and TLSA, in the case of TLSA to rule out OpenSSL3 being an issue i have tried linking against locally built OpenSSL 3.0.5 and OpenSSL 1.1.1q with identical results

I am in the process of repeating the build on Ubuntu 20.04 LTS to rule out weirdness with packages and similar issues i have experienced whilst evaluating 22.04 LTS ### Troubleshooting

#### Reproduction

<!-- If the issue can be reproduced, describe how it can be done. -->

#### 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. -->
