--- Comment #1 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
Also linker used is gold which may be a problem since:
So the problem ssems to be wrong call to strcmp:
Program received signal SIGSEGV, Segmentation fault.

$1 = 0x23896fb "x86-64"
(gdb) p processor_alias_table[i].name
$2 = 0x0

$3 = 0
processor alias table is const so i do not see how that can happen legally...

I've just tried to reproduce it:
../configure --with-build-config=bootstrap-lto --enable-checking=release
--disable-plugin
But the build is fine for me.

On our dhcp230 (zen III machine) it works if you make system linker ld,
if system linker is gold (from tumbleweed) it fails

I will rebuild and produce resolution files, looks like linker bug to
me.

Works on the branch.

Ah, my bad, I used BFD.

Note that this isn't ld.gold from openSUSE Tumbleweed. We still have 2.35.1
release in the distribution. This must be a built gold from source files?

Ah, you are right. It is binutils trunk (unpatched). Will figure out
what is going on here.

Good! If the failure happens quickly, you can likely bisect binutils quickly.
In which build stage do you see the failure?

I really cannot reproduce it with a custom ld.gold build.
