*** Stack backtraces
GDB's core code base has been updated to use a new backtrace
mechanism. This mechanism makes it possible to support new features
such DWARF 2 Call Frame Information (which in turn makes possible
backtraces through optimized code).
Since this code is new, it is known to still have a few problems:
gdb/1505: [regression] gdb prints a bad backtrace for a thread
When backtracing a thread, gdb doesn't stop until it hits garbage.
This is sensitive to the operating system and thread library.
When backtracing a thread, gdb does not stop when it reaches the
outermost frame, instead continuing until it hits garbage. This is
sensitive to the operating system and thread library.

GDB's SPARC, MIPS and PowerPC targets, in 6.0, have not been updated
to use the new frame mechanism.
The MIPS and HPPA backtrace code has only very recently been updated
to use GDB's new frame mechanism. At present there are still a few
problems, in particular backtraces through signal handlers do not
work.
People encountering problems with these targets should consult GDB's
web pages and mailing lists (http://www.gnu.org/software/gdb/) to see
if there is an update.

GDB's ARM target, in 6.0, has not been updated to use the new frame
mechanism.
PowerPC architecture support, in 6.1, does not use the new frame code.
Fortunately the ARM target, in the GDB's mainline sources, has been
updated so people encountering problems should consider downloading a
more current GDB (http://www.gnu.org/software/gdb/current).
Fortunately, PowerPC architecture support, in GDB's mainline sources,
have been updated. People encountering problems should consider
downloading a more current snapshot of GDB
(http://www.gnu.org/software/gdb/current/).
