Subject: Give mapped_index_base a virtual destructor
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6555809e3e5ca516c7c1ffca494118ec7fd16934;p=binutils-gdb.git

Give mapped_index_base a virtual destructor

This changes mapped_index_base to have a virtual destructor, so it can
be destroyed via its base class.
