045c55b2a2 Be conservative in all pointer derefrences by default. 
Since most people can't completely control their compile or runtime
environment, it becomes hard to ensure that unwind data is perfect.

f252f5ff4e Recognise and unwind through PLT. 2010-04-24 19:21:26 -07:00
Lassi Tuura
a9dce3c06e During the stack unwinding process, the return address points to 
the instruction after the call for a normal frame. libunwind uses
IP-1 to lookup unwind information. However, this is not necessary for
interrupted frames such as signal frames (or interrupt frames) in
the kernel context.

This patch handles both cases correctly.

Based on work by Mark Wielaard <mwielaard@redhat.com>
