test case

I have an issue were I get an "assertion fail ../../bfd/elf32-arm.c:12264" when
I link a shared library which links itself two static libraries and hides the
symbols using the "--exclude-libs ALL" switch. The sources are build with
-ffunction-sections and -fdata-sections and at link time --gc-section is used.
When removing --gc-sections or --exclude-libs the problem disappears.

See the attached testcase (tar containing 3 short C files and a Makefile which
you need to adapt for the right compiler name since it is an arm cross
compiler)

Actually the output is currently:

$ make
../bin/arm-PP-linux-uclibcgnueabi-gcc -fPIC -ffunction-sections -fdata-sections
-c -o test.o test.c
../bin/arm-PP-linux-uclibcgnueabi-gcc -fPIC -ffunction-sections -fdata-sections
-c -o test1.o test1.c
rm -f libtest1.a
../bin/arm-PP-linux-uclibcgnueabi-ar cru libtest1.a test1.o
../bin/arm-PP-linux-uclibcgnueabi-gcc -fPIC -ffunction-sections -fdata-sections
-c -o test2.o test2.c
rm -f libtest2.a
../bin/arm-PP-linux-uclibcgnueabi-ar cru libtest2.a test2.o
../bin/arm-PP-linux-uclibcgnueabi-gcc -shared -o libtest.so test.o
-Wl,--gc-sections,--exclude-libs,ALL -L. -ltest2 -ltest1
/opt/pp_toolchain/cross/008/bin/../lib/gcc/arm-pp-linux-uclibcgnueabi/4.6.3/../../../../arm-pp-linux-uclibcgnueabi/bin/ld:
BFD (Linux/GNU Binutils) 2.22.52.0.2.20120424 assertion fail
../../bfd/elf32-arm.c:12264

Looking at the code I saw that there was some recent activity where the assert
is generated (PLT ref count book-keeping check). Probably some case was
overlooked?!
