Rspamd is exiting with a core dump on launch

[Sbyrr0]

Same issue here (Manjaro ARM).

Using rspamd v 2.52 and kernel 5.4.51-1 on a Raspberry Pi 2 host
If I install rspamd on my computer it works normally (kernel 5.7.9 )

I can't install a previous version due to its linking against specific libraries
Anyone facing the same problem? How can I retrieve some logs?

gdb returns this:
$this->bbcode_second_pass_code('', 'Program received signal SIGSEGV, Segmentation fault.
0x76e24d5c in lpeg_allocate_mem_low () from /usr/lib/rspamd/librspamd-server.so')
