From f251cb9bae76441b43b3ea0b030086052eb54524 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Tue, 14 Feb 2023 14:23:25 -0500 Subject: [PATCH] gdb: use std::string for internalvar::name Change internalvar::name to std::string, automating memory management. It becomes necessary to allocate internalvar with new instead of XNEW. I didn't find how to trigger the code in complete_internalvar. It is called from condition_completer, so it should be by using the "condition" command, but I never managed to get in the right code path.
