Add a new python file to help diagnose backtrace failures in the field.
...
It will be installed in the LLDB.framework and can be loaded with
(lldb) script import lldb.macosx
after which a "unwind-diagnose" command will be registered. Select
the thread which has a bad backtrace and run this command -- a lot
of information about the stack frames, and an alternate backtrace
algorithm, will be used. The information will often be sufficient
for a remote person to figure out why the backtrace failed.

[analyzer] Treat reinterpret_cast like a base cast in certain cases.
...
The analyzer represents all pointer-to-pointer bitcasts the same way, but
this can be problematic if an implicit base cast gets layered on top of a
manual base cast (performed with reinterpret_cast instead of static_cast).
Fix this (and avoid a valid assertion) by looking through cast regions.
Using reinterpret_cast this way is only valid if the base class is at the
same offset as the derived class; this is checked by -Wreinterpret-base-class.
In the interest of performance, the analyzer doesn't repeat this check
anywhere; it will just silently do the wrong thing (use the wrong offsets
for fields of the base class) if the user code is wrong.

Summary:
This is http://llvm.org/PR15802 . Backslashes preceding double quotes in
arguments must be escaped. The interesting bit is that all other
backslashes should *not* be escaped, because the un-escaping logic is
only triggered by the presence of a double quote character.
