Debian Bug#1004269: Linker segfault while building src:xen

[Hans van Kranenburg <hans@xxxxxxxxxxx>]

(To both the Debian bug # and xen-devel list, reply-all is fine)
Hi Xen people,

I just filed a bug at Debian on the binutils package, because since the 
latest binutils package update (Debian 2.37.50.20220106-2), Xen (both 
4.14 and 4.16) fails to build with a segfault at the following point:
x86_64-linux-gnu-ld -mi386pep --subsystem=10 
--image-base=0xffff82d040000000 --stack=0,0 --heap=0,0 
--section-alignment=0x200000 --file-alignment=0x20 
--major-image-version=4 --minor-image-version=16 --major-os-version=2 
--minor-os-version=0 --major-subsystem-version=2 
--minor-subsystem-version=0 --no-insert-timestamp --build-id=sha1 -T 
efi.lds -N prelink.o 
/builds/xen-team/debian-xen/debian/output/source_dir/xen/common/symbols-dummy.o 
-b pe-x86-64 efi/buildid.o -o 
/builds/xen-team/debian-xen/debian/output/source_dir/xen/.xen.efi.0xffff82d040000000.0 
&& :
Segmentation fault (core dumped)

Full message and links to build logs etc are in the initial bug message, 
to be seen at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1004269
We (Debian Xen Team) are awaiting response, but I thought to also let 
you know already.
* Does the above error 'ring a bell'?
* Can you maybe also reproduce this in a development environment with 
very latest binutils?
* Maybe someone has a useful comment for the Debian binutils maintainer 
about what's happening in this step of the build?
* Any suggestions about what we can do to help figure this out?
* We'll try to help debug, but will surely appreciate upstream help if 
things get too technical. It's simply the case that I did not have to 
look into a very similar issue before, so it's new.
Thanks!
Hans
