I register_frame is used to enable the debugger (gdb) to debug JIT'd code.  It
is a function provided by libgcc, to be more precise in libgcc_eh.  Is it in
your copy?

$ nm libgcc_eh.a | grep register_fram
0000000000001960 T __deregister_frame
0000000000001950 T __deregister_frame_info
0000000000001830 T __deregister_frame_info_bases
0000000000001750 T __register_frame
0000000000001740 T __register_frame_info
00000000000016b0 T __register_frame_info_bases
0000000000001800 T __register_frame_info_table
0000000000001780 T __register_frame_info_table_bases
0000000000001810 T __register_frame_table

Ciao, Duncan.
