hidden symbol `__bb_fork_func' in /usr/lib/gcc-lib/i486-linux/3.3.5/libgcc.a(_bb.oS) is referenced by DSO

I have been googling for this error but I cannot find anything
relevant. Could someone please let me know how to track down the issue
I am having. I am trying to build shared libs with coverage info, and
then linking an executable to this library. When linking the linker
tells me:
/usr/bin/c++ -g -O0 -Wall -W -Wshadow -Wunused-variable -Wunused-
parameter -Wunused-function -Wunused -Wno-system-headers -Wno-
deprecated -Woverloaded-virtual -Wwrite-strings -fprofile-arcs -ftest-
coverage -Wno-deprecated -fPIC -fprofile-arcs -ftest-coverage

Thanks for any info

The worse part is that symbol is there:
$ nm /usr/lib/gcc-lib/i486-linux/3.3.5/libgcc.a | grep fork
00001130 T __bb_fork_func
I just can't get it to work...
