--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I tried to build into an executable but there are so many undefined symbols it
didn't work.
With shared library:
[apinski@xeond2 upstream-gcc-match]$ ~/upstream-gcc/bin/gcc -O2 -g ~/src/eval.i
-shared -fPIC -fno-semantic-interposition
[apinski@xeond2 upstream-gcc-match]$ nm a.out | grep -E
'backtrace_(next|function)'
0000000000007ac0 T backtrace_function
0000000000006759 t backtrace_function.cold
0000000000006740 t backtrace_function.part.0
00000000000078d0 T backtrace_next
[apinski@xeond2 upstream-gcc-match]$ !gdb
gdb -ex 'print backtrace_next' -ex 'print backtrace_function' a.out

Reading symbols from a.out...
$1 = {union specbinding *(union specbinding *)} 0x78d0 <backtrace_next>
$2 = {Lisp_Object (union specbinding *)} 0x6740 <backtrace_function>
(gdb) quit
So this looks to be a gdb issue with respect to an relocated object file and
not a debugging information produced by GCC.
