- Fix "??" resolving of symbols from (non-prelinked) debuginfo packages.
- Fix "??" resolving of symbols from overlapping functions (nanosleep(3)).
- Also disable testcase "checkpoint.exp" for a possible kernel Bug 207002.
- Improved testsuite results by the testsuite provided by the courtesy of
BEA.
- Related: rhbz#179399
Note: i386 test results of the BEA testsuite uuencode(1)d for `gdb2fail.sh'
are too bogus, retest (RHTS?) required on the matching kernel.
`WONTFIX' by makem.

+ * 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 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
|
||||
