Problem building perl-5.40.0 using gcc-14.1.0 (release 2, runtime 12.0.0)

[sisyphus]

This is an issue that's specific to runtime 12.0.0.
It doesn't arise with gcc-14.1.0 release 1, runtime 11.0.1.
Incidentally, these "r2" builds do not yet appear at http://winlibs.com. I don't know why that is.
The one that's producing this issue for me is:
https://github.com/brechtsanders/winlibs_mingw/releases/download/14.1.0posix-18.1.7-12.0.0-ucrt-r2/winlibs-x86_64-posix-seh-gcc-14.1.0-mingw-w64ucrt-12.0.0-r2.7z

During the build, everything goes fine until I get hammered with:

windres --use-temp-file --include-dir=. --include-dir=.. -O COFF -D INCLUDE_MANIFEST -i perlexe.rc -o .\perlexe.res
windres: bfd_set_arch_mach(aarch64): cause of error unknown
make: *** [GNUmakefile:811: .\perlexe.res] Error 1

I'm just wondering if anyone here has any hints as to where that bfd_set_arch_mach(aarch64) directive is coming from (and why it arises).
The string "bfd_set_arch_mach" does not appear anywhere in the perl source.

For reference, the actual perl bug report is at Perl/perl5#22266.

AFTERTHOUGHT: In case it's relevant, I'm running Windows 11.

Cheers,
Rob

Please use the GCC 14.1.0 r1 build until we figure out this issue.

For now we know it's related to the added platform support in binutils in this release.

Thanks @brechtsanders - now confirmed as not a perl bug

UPDATE: Ooops ... I meant to close the perl issue, not this one.
I'm happy for this to be re-opened if that's deemed desirable.

'NOTHER UPDATE: This issue has been resolved in the revised "r2" files that have now been uploaded.
(This issue is now definitely closable.)
