Seems to be recursing in cancel_option until stack runs out:
Breakpoint 5, cancel_option (opt_idx=30, next_opt_idx=0, orig_next_opt_idx=555)
    at /opt/build/gcc-4.2.3/gcc/opts-common.c:118
118       if (cl_options [next_opt_idx].neg_index == opt_idx)
(gdb) n
121       if (cl_options [next_opt_idx].neg_index != orig_next_opt_idx)
(gdb) 
122         return cancel_option (opt_idx, cl_options [next_opt_idx].neg_index,
(gdb)

118       if (cl_options [next_opt_idx].neg_index == opt_idx)

118       if (cl_options [next_opt_idx].neg_index == opt_idx)
