I don't get the relation with the debug mode, but there must be
something different with the pci table symbols for this driver.

My bet is on drivers/crypto/cnxk/cn9k_cryptodev.c:
static struct rte_pci_id pci_id_cpt_table[] = {
        {
        },
        /* sentinel */
        {
                .device_id = 0
        },
};

Adding some pci id, like the cn9k vf cpt pci id, will likely fix the issue.
And as a bonus, this will make this driver actually do something.


- There is also another issue with clang + debug.
This seems rather old, nobody complained.
Fixed with:
