In an own project which worked for years, the linker suddenly aborts with
/usr/bin/ld: BFD 18.104.22.168.7 20031029 Debian GNU/Linux internal error, aborting
at ../../bfd/elf32-i386.c line 2247 in elf_i386_relocate_section
I broke my app down to a small testcase which I will try to append to this
bugreport. My system is Debian/sid.

Small test app which is the minimal version to reproduce the bug on my system.
Rreproduces the bug on my system.
I could not reproduce this problem with current mainline binutils and
gcc-3.3.3-hammer. There have been quite a few changes to elf32-i386.c since
binutils-22.214.171.124.7 and it's likely that one of them has fixed the bug. Please
try your testcase with a newer binutils. If current mainline binutils fails for
you, then we need the set of object files involved in the link rather than C/C++
source files. Compiler differences may make it impossible to reproduce.

Object files that reproduce the bug with binutils 2.15
I updated binutils to the current mainline (2.15), but the ld-error remains. I
attached an archive with the modules which make the following line crash.
g++ -g -O2 -o test main.o modules/.libs/libmodules.a
/usr/bin/ld: BFD 2.15 internal error, aborting at ../../bfd/elf32-i386.c line
2262 in elf_i386_relocate_section
This is a relocation against a local symbol in a removed linkonce section.
Various hacks have been tried to handle such symbols and each one fails in some
cases, so I'm inclined to say this is really a problem with your c++ compiler.
HJ was the last person to touch the relevant linker code. He might have a
better idea than I whether anything can be done with this particular testcase.
I can reproduce it with gcc 3.3.5 20040627 and gcc 3.4.1 20040627.
It is a nasty problem, which can only be properly solved with comdat group.
Here is the linker patch
