From 6f5dad7d06620b4665303c542549d4c14f9fe784 Mon Sep 17 00:00:00 2001 From: Jiri Slaby <jirislaby@gmail.com> Date: Sat, 19 Feb 2011 13:26:35 +0100 Subject: [PATCH] collections: hash, fix double free We should not free the hash entry in antlr3HashFree when we didn't strdup on that earlier. I.e. make the free depend on table->doStrdup.
