configure of gcc:
--with-cpu=native --with-arch=native --disable-libsanitizer
--enable-checking=yes,rtl,extra
On cascadelake.
Remove --with-cpu=native --with-arch=native seems hide the issue.

Yes, that's the problem. Sorry about that, will send a patch with the fix
shortly.

--- Comment #7 from Eugene Rozenfeld <erozen at microsoft dot com> ---
No, locus won't be changed by the loop. But the purpose of the loop is to
change statement locations (by adding discriminators) in this line:
gimple_set_location (stmt, dloc);
I think the code would more clear if this line
location_t locus = last ? gimple_location (last) : UNKNOWN_LOCATION;
were moved to after the loop.
I'll include that change in the patch.

https://gcc.gnu.org/g:80f414e6d73f9f1683f93d83ce63a6a482e54bee
commit r13-3213-g80f414e6d73f9f1683f93d83ce63a6a482e54bee
Author: Eugene Rozenfeld <erozen@microsoft.com>
Date: Mon Oct 10 14:10:31 2022 -0700
Fix PR107193.
The bug was introduced in f30e9fd33e56a5a721346ea6140722e1b193db42.
A variable (cur_locus_e) was incorrectly declared inside a loop.
I also moved two other declarations (last and locus) down to make
the code more clear.
Tested on x86_64-pc-linux-gnu.
gcc/ChangeLog:
PR debug/107193
* tree-cfg.cc (assign_discriminators): Move declaration of
cur_locus_e
out of the loop.
