From 2d79090eabe8aa972b07cb71a3dd73ef9498acfa Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Mon, 14 May 2018 09:34:00 -0600 Subject: [PATCH] Clear rust_unions in rust_union_quirks It turns out that a dwarf2_cu can remain allocated after psymtab expansion is done, and so it makes sense to clear rust_unions when done processing it.
