            Bug ID: 30409
           Summary: mingw ar broken since binutils 2.33
           Product: binutils
           Version: 2.33
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

step 1 and 2 result of libkernel32.a

The last working version of binutils which makes a mingw (x86) -> mingw64-64
(x86/x64) build possible for me is version 2.32. I am able to build binutils
2.40 for example, but building mingw-w64-crt 10.0.0 later fails with the
following error:
x86_64-w64-mingw32-ranlib.exe: lib32/libkernel32.a: file format not recognized

The last steps to create this library were the following:
x86_64-w64-mingw32-dlltool --as-flags=--32 -m i386 -k
--as=x86_64-w64-mingw32-as --output-lib lib32/libkernel32.a --temp-prefix
$(basename lib32/libkernel32.a .a)  --input-def
../../src/mingw-w64-v10.0.0/mingw-w64-crt/`echo lib32/libkernel32.a | /bin/sed
's|/lib|/|;s|\.a|.def|'`

Step 2 results in a broken archive whereas the step 1 result still looks ok
from what I can see.
Please find attached both files. libkernel32.a after step 1 and after step 2.

P.S.: I have also included the result of the case that libkernel32.a is not
present when running step 2 (namely step2b).
