From f2440332caa2641e8615a9464c39acc49a892960 Mon Sep 17 00:00:00 2001 From: Alexey Bataev Date: Wed, 7 Oct 2015 10:22:08 +0000 Subject: Fix crash in codegen on casting to `bool &`. Currently codegen crashes trying to emit casting to bool &. It happens because bool type is converted to i1 and later then lvalue for reference is converted to i1*. But when codegen tries to load this lvalue it crashes trying to load value from this i1*.
