Make dwarf_expr_context's destructor virtual
Ref: https://sourceware.org/ml/gdb-patches/2016-10/msg00662.html
$ make WERROR_CFLAGS="-Wnon-virtual-dtor" dwarf2expr.o
...
In file included from .../src/gdb/dwarf2expr.c:28:0:
.../src/gdb/dwarf2expr.h:68:8: warning: ‘struct dwarf_expr_context’ has virtual functions and accessible non-virtual destructor [-Wnon-virtual-dtor]
struct dwarf_expr_context
^~~~~~~~~~~~~~~~~~
Happens to not be a problem in practice currently because concrete
subclasses are allocated on the stack. I.e., we don't ever delete
objects of types that derive from dwarf_expr_context through pointers
to dwarf_expr_context.
gdb/ChangeLog:
2016-10-25 Pedro Alves <palves@redhat.com>
* dwarf2expr.h (struct dwarf_expr_context) <~dwarf_expr_context>:
Make virtual.
