From 2f4732b0e622d9d5d899c29e2132e4cd2966aaad Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Fri, 3 Nov 2017 14:55:39 -0600 Subject: [PATCH] Remove symbolp vector This removes the symbolp typedef from dwarf2read.c and converts the associated VEC uses to std::vector. This fixes a latent possible memory leak if an exception were thrown, because there were no cleanups installed for these VECs. Regression tested on the buildbot. gdb/ChangeLog 2017-11-08 Tom Tromey * dwarf2read.c (symbolp): Remove typedef. (read_func_scope): Use std::vector.
