Debugging with GDB (September 2007)
Chapter 21: The gd b/mi Interface 305
‘level ’ The frame number, 0 being the topmost frame, i.e. the innermost function.
‘addr ’ The $pc value for that frame.
‘func ’ Function name.
‘file ’ File name of the source file where the function lives.
‘line ’ Line number corresponding to the $pc.
If invoked without arguments, this command prints a backtrace for the whole stack. If
given two integer arguments, it shows the frames whose levels are between the two arguments
(inclusive). If the two arguments are equal, it shows the single frame at the corresponding
level.
GDB command
The corresponding GDB commands are ‘backtrace’ and ‘where’.
Example
Full stack backtrace:
(gdb)
-stack-list-frames
^done,stack=
[frame={level="0 ",addr="0x0001076c",func="foo",
file="recursive2.c",line="11"},
frame={level="1 ",addr="0x000107a4",func="foo",
file="recursive2.c",line="14"},
frame={level="2 ",addr="0x000107a4",func="foo",
file="recursive2.c",line="14"},
frame={level="3 ",addr="0x000107a4",func="foo",
file="recursive2.c",line="14"},
frame={level="4 ",addr="0x000107a4",func="foo",
file="recursive2.c",line="14"},
frame={level="5 ",addr="0x000107a4",func="foo",
file="recursive2.c",line="14"},
frame={level="6 ",addr="0x000107a4",func="foo",
file="recursive2.c",line="14"},
frame={level="7 ",addr="0x000107a4",func="foo",
file="recursive2.c",line="14"},
frame={level="8 ",addr="0x000107a4",func="foo",

frame={level="9 ",addr="0x000107a4",func="foo",
file="recursive2.c",line="14"},
frame={level="10",addr="0x000107a4",func="foo",
file="recursive2.c",line="14"},
frame={level="11",addr="0x00010738",func="main",
file="recursive2.c",line="4"}]
(gdb)
Show frames between low frame and high frame:
