Hi,
After set debug frame 1, while running the run command I have log the
output mentioned below, after this if I give "info frame" command, it's
completely crashes and closed the complete gdb.

*************************gdb.txt****************************************

{ frame_id_p (l={stack=0x0,code=0x0,special=0x0}) -> 0 }

{ frame_id_p (l={stack=0x0,code=0x0,special=0x0}) -> 0 }
{ frame_id_p (l={stack=0x0,code=0x0,special=0x0}) -> 0 }

{ deprecated_update_frame_pc_hack (frame=-1,pc=0x1a8) }

Breakpoint 1, main () at test.c:2

set debug frame 1 and send the output on the list. Maybe someone can
then see the error.
