            Bug ID: 28867
           Summary: Mingw to generate bogus.o on French locale
           Product: binutils
           Version: 2.37
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: eric.pouech at orange dot fr
  Target Milestone: ---

Following report to gcc https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104399

after adding one letter to a string inside a .c program, compilation and link
fails with:

/usr/lib/gcc/i686-w64-mingw32/11.2.1/../../../../i686-w64-mingw32/bin/ld:
warning: dlls/dxdiagn/provider.cross.o: local symbol `�' has no section
/usr/lib/gcc/i686-w64-mingw32/11.2.1/../../../../i686-w64-mingw32/bin/ld:
dlls/dxdiagn/provider.cross.o: unrecognized storage class 0 for *UND* symbol
`�'
/usr/lib/gcc/i686-w64-mingw32/11.2.1/../../../../i686-w64-mingw32/bin/ld:
dlls/dxdiagn/provider.cross.o: could not read symbols: file format not
recognized

I won't post source code (not because I cannot, but because it won't help).
Issue really looks like an issue with generating the .o data inside the file,
not the content of the .c file itself.

will compare three operations:
- make without letter change in .c (good.o)
- make with letter change in .c (fail.o)
- make with letter change in .c and forcing English locale (LC_ALL=C make)
(good-eng.o)

(the two first are generated with French locale)

[eric]$ echo $LANG
fr_FR.utf8

result of compilations:
- like the names imply: good.o and good.eng are ok
- while fail.o generates the errors above

------------------

doing some binary diffs (%.o => %.txt with xxd %.o %.txt)

[eric]$ diff good.txt good-eng.txt 
1416,1417c1416,1417
< 00005870: 7665 6e64 6f72 2049 4420 3078 2530 3478  vendor ID 0x%04x
< 00005880: 2e0a 0000 7300 7a00 4d00 6100 6e00 7500  ....s.z.M.a.n.u.

that's the only diff; just exposing the change in the string (luckily
short-alignment didn't shift the rest of the file)

now the diff with the bogus.o file

[eric]$ diff -C 3 good.txt fail.txt

looking at gcc intermediate files (-save-temps)

generating the good.s, good-eng.s and fail.s (with same naming conventions as
in #1)
[eric]$ diff good.s good-eng.s
7812c7812
<       .ascii "Unknown PCI vendor ID 0x%04x.\12\0"
---
>       .ascii "Unknown PCI vendor ID 0x%04lx.\12\0"
adding the letter to the string (only diff of two .s files)

[eric]$ diff fail.s good-eng.s
no difference shown...

so forwarding to binutils at gcc bz requests ;-)

I didn't attach the various files because of their size. I can of course
provide them and do further action on them, whatever is needed.
