__register_frame_info comes from libm, I think.

 % objdump --dynamic-sym /lib/libc.so.6 | grep register_frame_info
 % objdump --dynamic-sym /lib/libm.so.6 | grep register_frame_info
 000134dc g    DF .text  0000005d __deregister_frame_info
 000133f0 g    DF .text  0000004a __register_frame_info
 00013468 g    DF .text  00000046 __register_frame_info_table
