60b7af702a (dwarf_find_save_locs): Add a comment. 
Now that dwarf_find_save_locs() not just finds the save-locations but
also updates the cursor-state, document this fact (the function really
is misnamed now).

8c94e12429 (_UPT_find_proc_info): Fix potential crash due to uninitialized pointer. 
Be sure to clear pi->unwind_info when looking up the kernel table and
not needing the unwind-info.  Otherwise, _UPT_put_unwind_info() may
erroneously call free() on the pointer, even though that space wasn't
malloc'd, leading to crashes..

af2503e223 Fix bug in libunwind-ptrace which can cause reading of random data. 
(maps_next): After reading less than a full buffer of data, copy
remaining data to the top of the buffer so as to maintain the
invariant that all data between mi->buf and mi->buf_end is valid.
This avoids maps_next() parsing uninitialized data.

f176ad6fc6 Bring git v0.98.5 tree in sync with released v0.98.5. 
Sadly, the conversion from Bitkeeper -> CVS -> git wasn't perfect.  Or
so it seems.
