[Bug ld/5522] New: Section contents partially overwritten with zero

[SebastianR at gmx dot de]

Hello!

When linking the attached files using the command line

  ld -q -T bss.lds attention.o libbss.a -o attention.bso

with ld 2.18 targeted for ELF (tested on Linux with version 2.18-1 from Debian,
and on Windows by building binutils 2.18.50 on MinGW with target "i386-pc-elf"),
the first 8 bytes of the section ".bs.server.name" are overwritten with zero. 
I.e.,

  objdump -s -j .bs.server.name attention.o

gives

  Contents of section .bs.server.name:
   0000 41747465 6e74696f 6e536967 6e00      AttentionSign.

whereas

  objdump -s -j .bs.server.name attention.bso

gives

  Contents of section .bs.server.name:
   400620 00000000 00000000 6e536967 6e00      ........nSign.

A similar problem occurs with the file "car.o"; in that case the entire contents
of ".bs.server.name" and ".bs.server.service" come out as zero. The section
lengths are correct, however.

Many similar files are linked just fine, but the problem is reproducable with
these specific files, even though it looks pretty random to me. There are no
relocs in the affected sections, so the section contents should stay exactly the
same IMHO.

Please mail me if you want to generate the files yourself.

Thanks,
Sebastian Reichelt
