### Prerequisites
> * [ ] Put an X between the brackets on this line if you h…ave done all of the following:
> * Read about bug reporting in general: https://rspamd.com/doc/faq.html#how-to-report-bugs-found-in-rspamd
Done.
> * Enabled relevant debugging logs: https://rspamd.com/doc/faq.html#how-to-debug-some-module-in-rspamd
Not module related, not applicable, not done.
> * Checked the FAQs about Core files in case of fatal crash: https://rspamd.com/doc/faq.html#how-to-figure-out-why-rspamd-process-crashed
Done.
> * Tried ASAN package and obtained the ASAN report (if possible): https://rspamd.com/doc/faq.html#asan-builds
Done. (Described below in this report.)
> * Checked that your issue isn't already filed: https://github.com/issues?utf8=%E2%9C%93&q=is%3Aissue+user%3Arspamd
* https://github.com/rspamd/rspamd/issues/399 looks similar, that's why I am already providing all debug output you might ask for but that issue is old and says was resolved.
> * Checked that there is not already an experimental package or master branch
Not experimental / master branch.
### Steps to Reproduce
rspamd --version
(But `--version` is just to show that there is a grave issue here. `rspamd` is totally broken, unsuable for me on that system.)
### Expected behavior
Show version, no error.
### Actual behavior
```
zsh: illegal hardware instruction rspamd --version
```
### Versions
`3.9.1-1` from rspamd repository.
> Setting up rspamd (3.9.1-1~82f43560f~bookworm) ...
> Setting up rspamd-dbg (3.9.1-1~82f43560f~bookworm) ...
```
lsb_release -a
```
```
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 12 (bookworm)
Release: 12
Codename: bookworm
```
Actually, Kicksecure which comes with [security-misc](https://github.com/Kicksecure/security-misc), which enables a lot of kernel security related kernel parameters and sysctl.
### Additional Information

Why did I attach the CPU info of both, a broken machine and a functional machine? Because I am suspecting this could be CPU related. The broken CPU for example lacks a few CPU flags such as `avx`.
In summary:
* `model name : Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz` - issue
* `model name : Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz` - no issue

## ASAN build
How about ASAN builds?
It does not create a core file. I have no idea why. Only rspamd / rspamd-dbg version creates core files. Why rspamd-asan does not create core files I don't know. Should be the same, right? Once I figured out how to create core files it should always be functional?
```
rspamd --version
```
```
zsh: illegal hardware instruction rspamd --version
```
```
ls -la /coreland
