sol nonfunctional with clang's -ftrivial-auto-init=zero

[lattera]

When building ipmitool on HardenedBSD 14-CURRENT/amd64 with -ftrivial-var-auto-init=zero, the following command results in zero output from the system:

ipmitool -I lanplus -H IPv4_address_sanitized -U adminuser_sanitized -P adminpassword_sanitized sol activate

Effectively, sol activate becomes non-functional.

To test: Install the latest HardenedBSD 14-CURRENT/amd64 build, then run pkg install ipmitool and use ipmitool like usual.

Description    :
Quoting IPMItool homepage:

"IPMItool is a utility for managing and configuring devices that
support the Intelligent Platform Management Interface (IPMI) version
1.5 and version 2.0 specifications. IPMI is an open standard for
monitoring, logging, recovery, inventory, and control of hardware that
is implemented independent of the main CPU, BIOS, and OS."

FreeBSD has OpenIPMI-compatible ipmi(4) driver for in-band IPMI
operations in the base system starting from 6.2 release. On older
systems sysutils/ipmi-kmod port is available.

Does it happen only with 1.18 or is the current version from github sources is also affected?
