Fix 'gcore' with exited threads
Program received signal SIGABRT, Aborted.
[...]
(gdb) gcore foobar
Couldn't get registers: No such process.
(gdb) info threads
[...]
(gdb) gcore foobar
Saved corefile foobar
(gdb)
gcore tries to access the exited thread:
[Thread 0x7ffff7fce700 (LWP 6895) exited]
ptrace(PTRACE_GETREGS, 6895, 0, 0x7fff18167dd0) = -1 ESRCH (No such process)
Without the TRY_CATCH protection testsuite FAILs for:
gcore .../gdb/testsuite/gdb.threads/gcore-thread0.test
Cannot find new threads: debugger service failed
(gdb) FAIL: gdb.threads/gcore-thread.exp: save a zeroed-threads corefile
+
core .../gdb/testsuite/gdb.threads/gcore-thread0.test
".../gdb/testsuite/gdb.threads/gcore-thread0.test" is not a core dump: File format not recognized
(gdb) FAIL: gdb.threads/gcore-thread.exp: core0file: re-load generated corefile (bad file format)
Maybe the TRY_CATCH could be more inside update_thread_list().
Similar update_thread_list() call is IMO missing in procfs_make_note_section()
but I do not have where to verify that change.
