Debugging with GDB Manual HP WDB v6.3 (5900-2180, August 2012)

The verbose description is useful when something has gone wrong that
has made the stack format fail to fit the usual conventions.
info frame addr,
info f addr
Print a verbose description of the frame at address addr, without selecting
that frame. The selected frame remains unchanged by this command. This
requires the same kind of address (more than one for some architectures)
that you specify in the frame command. See “Selecting a frame”
(page 56).
info args Print the arguments of the selected frame, each on a separate line.
info locals Print the local variables of the selected frame, each on a separate line.
These are all variables (declared either static or automatic) accessible at
the point of execution of the selected frame.
info catch Print a list of all the exception handlers that are active in the current stack
frame at the current point of execution. To see other exception handlers,
visit the associated frame (using the up, down, or frame commands);
then type info catch. See “Setting catchpoints” (page 42).
