That is correct.

I;m not aware of using optimizations on net/asterisk* ports themselfs but I have made a "make
rmconfig config" recently due to the same thought as of yours. On net/asterisk, I haven't
changed anything within the past few months, but I also do not track versions, my fault - so
the statement is a kind of useless. I also have no clue about faulty optimizations in
adjacent/required ports like those mutually transcribing codecs which are candidates for
vectore unit optimizations, I guess. What happened is: I exchanged my builder platform from
Intel based, much outdated Xeon Ivybridge to recent AMD Zen 5 based equipment. While  in the
bureau an older dual socket Intel Xeon performs the same task without problems, first guess is
a problem with compiling AMD Zen5 code.

That possibility sounds reasonable, see my comment on the hardware vendor change of the CPU. I
disabled all optimization flags as far I got a handle on them and/or being aware of, so the
host is just right now a complete new repository for 14-STABLE. It did not help just disabling
the optimization flag on both net/asterisk20 and net/asterisk22 (both suffer from the same
issue). Will report back.

Kind regards,
