9 | + * The point of this program is to crash in a multi-threaded app. | |
10 | + * There are seven threads, doing the following things: | |
11 | + * * Spinning | |
12 | + * * Spinning inside a signal handler | |
13 | + * * Spinning inside a signal handler executing on the altstack | |
14 | + * * In a syscall | |
15 | + * * In a syscall inside a signal handler | |
16 | + * * In a syscall inside a signal handler executing on the altstack | |
17 | + * * Finally, the main thread crashes in main, with no frills. | |
18 | + * | |
19 | + * These are the things threads in JRockit tend to be doing. If gdb | |
20 | + * can handle those things, both in core files and during live | |
21 | + * debugging, that will help (at least) JRockit development. | |
22 | + * | |
23 | + * Let the program create a core file, then load the core file into | |
24 | + * gdb. Inside gdb, you should be able to do something like this: | |
25 | + * | |
26 | + * (gdb) t a a bt | |
