gdb bug fix update

An updated gdb package that fixes various bugs is now available.

GDB, the GNU debugger, allows debugging of programs written in C, C++,
and other languages, by executing them in a controlled fashion, and then
printing their data.

This updated package addresses the following issues:

- GDB could not backtrace from the vsyscall (on non-i386 architectures).
The problem where GDB could not find symbols, or backtrace from, the
vsyscall page has been fixed.

- Single stepping of a thread exit would hang GDB. The problem where a
single-step off the end of a thread would hang gdb has been fixed.

- DW_AT_type <0> debug info would confuse GDB. Intel's ICC compiler
generates this debug info type. GDB now ignores it.

- GDB was not able to find source code when executable moved. The problem
with GDB not locating the original source when items were moved from their
build location has been fixed.

- GDB could not backtrace from system calls for code in the "vsyscall"
page. The code for backtracing out of the vsyscall page was only enabled on
the i386 architecture. It is now enabled across all architectures.

- Multilib conflicts (e.g., /usr/share/info/annotate.info.gz) have been
fixed, which include 32-bit and 64-bit GDBs.

- GCC generated two copies of a constructor resulting in erroneous GDB
behavior. Various segmentation faults and a strange ?HERE message in a
constructor breakpoint list have been fixed. A problem where GDB could not
correctly set a breakpoint has been fixed for all instances of a C++
constructor.

- Various problems on Itanium, including backtraces and corefiles, have
been fixed.

All users of gdb should upgrade to this updated package, which resolves
these issues.
