Yes, they were fixed on the trunk by:
commit 0f731c49e6a8ccf3aa4c30c3f8ca82ed0a2cefb7
Author: Paul Eggert <eggert@cs.ucla.edu>
AuthorDate: Thu May 12 17:01:10 2022 -0700
Pacify GCC 12 in default developer build
For instance:
* src/term.c (Fsuspend_tty): Don’t look at a pointer after freeing
it, even just to test it for equality with some other pointer, as
this has undefined behavior in C and GCC 12 diagnoses this.
