[Libunwind-devel] unw_get_proc_info never gets unwind info

[Doug Moore]

For x86_64, specifically, and for dwarf generally, unw_get_proc_info  
does not set the unwind_info field of the unw_proc_info_t to any  
non-NULL value, ever.  That is because dwarf_make_proc_info passes 0  
as the last argument to fetch_proc_info, so that  
dwarf_extract_proc_info_from_fde ends up not copying unwind info.

How can one get the actual unwind info out of unw_get_proc_info?
