In our SW build we have a pre-compiled library that is linked with gnuld:
ld -r -EL -o precompiled.a module1.o module2.o ...
When this library is linked together with other objects with gold I get an
internal error:
$ build/gold/ld-new -r -o test.a precompiled_gnuld.a
build/gold/ld-new: internal error in output_symtab_index, at
../../binutils-2.19/gold/object.h:968
If I create precompiled.a with gold from the same object files everything works
fine. The resulting libraries are different:
-rw-r--r-- 1 user group 2332299 2008-12-10 12:01 precompiled_gnuld.a
-rw-r--r-- 1 user group 2317681 2008-12-10 12:36 precompiled_gold.a

As I'm not allowed to distribute the precompiled library I hope you can tell me
what additional information I would need to collect for your error analysis.
