From FEDORA_PATCHES Mon Sep 17 00:00:00 2001
From: Fedora GDB patches <invalid@email.com>
Date: Fri, 27 Oct 2017 21:07:50 +0200
Subject: gdb-6.5-BEA-testsuite.patch
;; Improved testsuite results by the testsuite provided by the courtesy of BEA.
;;=fedoratest: For upstream it should be rewritten as a dejagnu test, the test of no "??" was useful.

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