The GDB 7.8 features are:
* Python Scripting
- You can now access frame registers from Python scripts.
- New attribute 'producer' for gdb.Symtab objects.
* New Python-based convenience functions:
- $_caller_is(name [, number_of_frames])
- $_caller_matches(regexp [, number_of_frames])
- $_any_caller_is(name [, number_of_frames])
- $_any_caller_matches(regexp [, number_of_frames])
* New commands
- queue-signal signal-name-or-number
Queue a signal to be delivered to the thread when it is resumed.
* On resume, GDB now always passes the signal the program had stopped
for to the thread the signal was sent to, even if the user changed
threads before resuming. Previously GDB would often (but not
always) deliver the signal to the thread that happens to be current
at resume time.
* Conversely, the "signal" command now consistently delivers the
requested signal to the current thread. GDB now asks for
confirmation if the program had stopped for a signal and the user
switched threads meanwhile.
* "breakpoint always-inserted" modes "off" and "auto" merged.
Now, when 'breakpoint always-inserted mode' is set to "off", GDB
won't remove breakpoints from the target until all threads stop,
even in non-stop mode. The "auto" mode has been removed, and "off"
is now the default mode.
* MI changes
- The -list-thread-groups command outputs an exit-code field for
inferiors that have exited.

Fix build failure in symfile.c::unmap_overlay_command (GCC5 bug)
|
|
|

Compilation of (GDB) 7.9.50.20150127-cvs with (GCC) 5.0.0 20150127

fails with

While the bug was reported to GCC as

<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64823>,
|
|
the attached patch simply initializes sec with NULL.

|
|
* symfile.c (unmap_overlay_command): Initialize sec to NULL.
