[Libunwind-devel] [PATCH] dwarf: allocate a debug frame index table with mmap()

[Sergey Korolev]

By analogy with "dwarf: do not allocate in load_debug_frame (#72)"

avoid to call realloc(). An index table is also created infrequently

and freed in unw_flush_cache() only.

    

The main idea of the patch is to calculate an index table size first

and then allocate a whole memory region.
