Sure. I've attached a tarball, containing the (trivial) source, together with
two variants of the executable, both compiled with:
{{{
$ mingw32-gcc -g -O0 foo.c -o foo-gcc-10.2.0-binutils-2.3x.exe
}}}
(with the respectively named binutils version installed in the
mingw32-gcc-10.2.0 path). The binutils-2.32 variant (which uses the same
binutils version as my GDB build) can be successfully debugged; the
binutils-2.38 variant cannot.
Also, maybe try using -gdwarf-2 when compiling the program, perhaps the problem
is due to the debug info, not the executable code.
-gdwarf-2 or -g makes no difference: binutils-2.32 is okay; binutils-2.38 is
not.
Thanks. I unpacked the archive, and GDB 12.1 that I built myself can debug
both executables without any trouble on native MS-Windows XPSP3. I've
successfully stepped through both programs from start to exit.
So I think there's no problem with the compiler, just with the debugger you
have there.

Ticket details:
The latest version of GCC, 9.2.0, available for MinGW development, was released
almost 2 years ago and last updated more than a year ago.
Would it be possible to provide a MinGW port of a newer GCC version, like 10 or
maybe even 11?
Thanks in advance.

I firmly believe that the maintainer needs to develop a solid understanding of
the build process, and that isn't going to be achieved by simply repeating,
parrot fashion, what I have done.
Yes, I agree. But reading patches and descriptions of configuration options
used by someone experienced frequently gives ideas and focuses attention on
important aspects of the build. It is not easy to find relevant optional
features in the output of configure --help, and their short descriptions
usually leave a lot of questions unanswered, and thus make the decisions
regarding them difficult.
I use mingw-pkg to manage my builds, and yes, I would be willing to publish the
package specification files, and patch sets, which I have used — in any case,
they are already included in the MinGW.OSDN source tarballs for each of the
packages which I have published. I am also prepared to answer any questions,
from a prospective new maintainer, to help him/her to get up to speed.
I have also begun to create web pages — each a work-in-progress, rather
incomplete, and as yet unpublished — to document mingw-pkg usage, and to
describe how I set about using it to build a GNU/Linux hosted GCC
cross-compiler. I could make them available, even in their incomplete state,
as preview editions, if deemed desirable. (FWIW, my mingw-pkg build
specifications, for both GCC and binutils, support building of both the
cross-compiler, and native-compiler — crossed-native, for my builds —
components, simply by adjustment of the mingw-pkg command line options).
Thanks, I think this will be very useful, should Someone(TM) decide to step up.

So I think there's no problem with the compiler, just with the debugger you
have there.
The debugger I have here is the same GDB-9.2 as can be found here; it was
compiled from original GDB sources, with no patches applied. The only oddity
is that the release encapsulates two distinct builds, one configured
--with-python, and one --without-python, (with distinctly renamed gdb.exe
variants), and the gdb.exe supplied is a simple wrapper, which delegates to one
or other of the renamed variants, depending on whether, or not, a LoadLibrary()
call can successfully load an appropriate python DLL.
I'm not convinced that there is actually anything wrong with my installed GDB;
rather, I suspect that you were on the right track, when you pointed to a
possible binutils issue. Both of the foo.exe variants, which I provided, were
compiled by identically the same mingw32-gcc-10.2.0 cross-compiler, the only
difference being in the version of binutils which was installed into that
compiler's working path, at the time of compilation. I do note that, within
the GDB-9.2 source tree, is an implementation of bfd which proclaims its
version to be 2.33.50, (so presumably abstracted from binutils-2.33.50); thus,
logically GDB-9.2 supports the ABI of bfd-2.33.50, (and maybe earlier).
Realistically, I don't expect guaranteed forward compatibility with any more
recent version of binutils, and sure enough, when I install binutils-2.32 —
earlier than the GDB-9.2 bfd version — into the compiler's working path, I can
successfully step through the resultant executables, in GDB-9.2; OTOH, when I
install either binutils-2.36.1, or binutils-2.38 — both more recent than the
GDB-9.2 bfd version — I cannot step through the resultant executables.
You can step through both of the executables, which I provided, with GDB-12.1.
Presumably this more recent GDB supports a more recent bfd ABI — at least
compatible with binutils-2.38, whilst remaining backward compatible at least as
far as binutils-2.32. If this is indeed the case, I don't think that your
ability to debug both of my executables is evidence of anything, other than an
ABI (forward) compatibility issue.
