There's a good chance GDB will panic during initialization ... - If it starts, the output from: (gdb) maint print architecture architecture (gdb) shell grep -i deprecated architecture I'm looking to see if/why legacy_frame_p() returns true/false (did that #if 1 really work?) - what happens when: ./gdb .../advance (gdb) break main (gdb) run (gdb) next ... is executed. I'm looking to see how/where GDB panics when stepping - this is testing the code's ability to unwind the PC register. - what happens when ./gdb .../advance (gdb) break func (gdb) run (gdb) advance func3 (it should end up in main) I'm looking to see if/how GDB is correctly unwinding frame IDs - this is testing the code's ability to keep a frame ID constant across a function.
