| 16 | # In this test we're looking at how gdb handles backtraces and | |
| 17 | # investigating the stack depth when confronted with an "invalid" stack, | |
| 18 | # that is a stack where the first few frames are normal, and then there's a | |
| 19 | # frame where the stack in unreadable. | |
| 20 | # | |
| 21 | # One interesting bug that has been observed is that gdb will sometime | |
| 22 | # exhibit different behaviour the first time a stack command is run | |
| 23 | # compared to the second (and later) times a command is run. This is | |
| 24 | # because the first time a command is run gdb actually tries to figure out | |
| 25 | # the answer, while the second (and later) times gdb relies on the answer | |
| 26 | # cached from the first time. As a result in this test each command is | |
| 27 | # run twice, and we restart gdb before testing each different command to | |
| 28 | # ensure that nothing is being cached. | |
